This is not a screen capture method, but a full level 1 and level 2 postscript driver. The postscript images generated are detailed and accurate as possible, given the resolution of the data, and the printing resolution. Postscript Level Level 1-- The postscript generated consist of a color lookup table and image data, encoded in ASCIIHEX. All line graphics and text are postscript elements. Level 2-- The postscript generated consist of a color lookup table and image data, compressed with RLE, and encoded in ASCIIHEX85. All line graphics and text are postscript elements. Postscript Color Model DS9 supports three color models for level 2 postscript. All three color models generate approximately the same size files. RGB CMYK Grayscale Resolution Most printers dither to achieve various levels of gray or color. So a 300 dpi printer's affective resolution may only be 53 dpi after dithering. This is fine for analysis and proofs. On the other hand, when generating images for publication, color separation is used to achieve the full resolution of the printer . A 150 dpi CMYK image will generate four 150 dpi images (one for each color). In general, select the lowest resolution possible, as postscript file size grows by the square of the increase. 81 XPA Access Points The XPA messaging system provides seamless communication between DS9 and other Unix programs, including X programs, Perl, S-Lang, and Tcl/Tk. It also provides an easy way for users to communicate with DS9 by executing XPA client commands in the shell or by utilizing such commands in scripts. Because XPA works both at the programming level and the shell level, it is a powerful tool for unifying any analysis environment. 2mass about analysis array bin blink catalog cd cmap colorbar console contour crosshair cursor data datacube dsssao dsseso dssstsci exit file first fits frame grid header height iconify iis imexam lock lower magnifier mask 82 match minmax mode nameserver nvss orient pagesetup pan pixeltable plot prefs preserve psprint print quit raise regions rgb rotate saveimage savefits savempeg scale shm single skyview sleep smooth source tcl tile update version view vo wcs web width zscale zoom 2mass Support for 2MASS Digital Sky Survey.

SCAN will scan all data. SAMPLE will sample the data every n samples. DATAMIN and IRAFMIN will use the values of the keywords if present. In general, it is recommended to use SCAN unless your computer is slow or your data files are very large. Select the increment interval for determining the min and max data values during sampling. The larger the interval, the quicker the process.

These analysis commands are defined at start-up time , or loaded by the user, by means of an ASCII analysis description file. The analysis commands are available for execution, either via the Analysis Menu or the XPA point Analysis. In addition, commands may be bound to events, such as keystrokes or mouse clicks. This type of command is called a bind command. At startup, DS9 first searches for the analysis file, named .ds9.ans,in the local directory, then in the users home directory. A second analysis file to load at startup may be specified in the preferences (Preferences : Analysis : Analysis File). The user may also load or clear current analysis commands via command line options or the Analysis menu. When activated, either from the menu, XPA, or bound event, an analysis command first is macro-expanded to fill in user-defined arguments and then is executed externally. Results may be displayed in a separate text window, plot window, or in a image frame. Syntax Command Type Macros Help Parameters Hierarchical Menus Sample Syntax The analysis file that defines the known analysis commands consists of one or more file descriptors, each of which has the following format: Menu label to be used A space separated list of file templates Command type [menu | bind <event>] The command line for the analysis program Task names may contain space characters. All lines may be indented. Also, the '#' character is a comment character. A separator can be inserted in the menu by specifying the following sequence '---'. Example: # this will insert a menu separator --- 132 Command Type The third line indicates the type of command. menu A menu command creates an menu option under the Analysis menu option, and can be invoked by the user via the GUI or XPA. Example: # Menu command example My Analysis Task *.fits menu $data | doit | $text bind A bind command is a command that is bound to an event. When the event occurs, the command is executed. Types of events available include all TK events, including all keystrokes and mouse clicks. If a command is bound to an event other that a keystroke, care must be taken to not to interfere with other internal DS9 events. To bind to a key stroke, use the following command type: bind <keystroke> Example: # Bind command example Print coordinates *.fits bind x echo "$x $y" | $text web A web command allows the user to invoke the internal web browser from the analysis menu. Example: # web command example HTTP based * web http://hea-www.harvard.edu/RD/ds9/ref/index.html File based * 133 web file:/home/joye/index.html Macros The following macros are macro-expanded to fill in user-defined arguments before the command is executed. Strings that contain $<macroname> that user does not want to be expanded may be escaped by using $$<macroname>. All strings that contain $<string> that are not a macro name will not be affected. For example: echo "$$data $foo" | $text will display a text dialog that contains "$data $foo" $width $height $depth Substitute the width, height, or depth of the data file in the command line. Syntax: $width $height Example: echo "$width $height $depth" | $text $bitpix Substitute the bitpix of the data file in the command line. Syntax: $bitpix Example: echo "$bitpix" | $text $data Data from the current frame becomes the input data to the command string. This data is in the form of a FITS image. This macro can only used at the beginning of the command string. Syntax: $data Example: $data | dosomething | $text 134 $entry Display an entry modal dialog. The returned string is substituted. If cancel is selected, the command line is not executed. Syntax: $entry(<message>) Example: echo "$entry(Enter something here)" | $text $env Substitute the value of a shell environment variable. Syntax: $env(<shell variable>) Example: echo "$env(PATH)" | $text $filedialog Display the standard file dialog. Substitutes the returned pathname. Argument specifies if an open file or save file dialog is invoked. Syntax: $filedialog([open|save]) Example: echo "$filedialog(open)" | $text $filename Substitute the filename of the data file in the command line. $filename(root) will return only the root filename. Syntax: $filename $filename(root) Example: dosomething $filename | $text dosomething $filename(root) | $text $filename[$regions] Combination of $filename and $regions macros. Generates a series of filenames, each with a region. Syntax: $filename[$regions] $filename[$regions(<options>)] 135 Example: dosomething $filename[$regions] | $text $geturl This macro differs from all other macros, including $url, in that no subprocess pipe is created. Only HTTP is supported. The contents of the url are retrieved and sent to $text, $plot, or $image. No other processing is allowed. The primary purpose of this macro is to support external analysis for the Windows platform, which has no subprocess support. Syntax: $geturl(http://<hostname>:<port>/<query>) Example: $geturl(http://foo.bar.edu/foo.html) | $text $image The resulting image data is display in a DS9 frame. This macro should be the last macro of a command line. Optional parameter indicates if a new frame is created for the new data. The macro is removed from the command line before execution. Syntax: $image $image([new|current]) Example: doit | $image(new) $message Display a message dialog box, with option buttons. After displaying the message, the macro is removed from the command line before execution. If cancel or no is selected, the command line is not executed. Syntax: $message(<message>) $message([ok|okcancel|yesno],<message>) Example: $message(okcancel,This is a Message)| doit | $text $null Expect no output or results from analysis task. Note: no error message will be returned if the analysis task fails to execute correctly. Syntax: $null Example: echo "Hello, world" > foo | $null 136 $pan Substitute current pan location of the particular data file are returned. The default coordinate system is physical. Syntax: $pan $pan(<coordinate system>,<format>) where: coordinate system = [image|physical|detector|amplifier|wcs|wcsa...wcsz] sky frame = [fk4|fk5|icrs|galactic|ecliptic] sky format = [hms|sexagesimal|degrees] Example: echo $pan(fk5,sexagesimal) | $text $plot Display data in plot window. This macro should be the last macro of a command line. The data is read via STDIN and consist of a pair of coordinates, with option error values. (xy, xyex, xyey, xyexey) Default dimension is xy. The macro is removed from the command line before execution. For $plot(stdin) only: The title, x axis label, and y axis label are assumed to be on the first line of input, delimited with a new-line. However, if the data starts with $BEGINTEXT, all text between $BEGINTEXT and $ENDTEXT will be removed from the data and displayed in a separate text dialog window, with the remaining data, including the title, x axis label, and y axis label, will be displayed in a plot window. Furthermore, if the data contains the string $ERROR, an error is assumed to have occurred and a text dialog window is displayed only. Syntax: $plot $plot(,,,) $plot(<title>,<x axis label>,<y axis label>,[xy|xyex|xyey|xyexey]) $plot(stdin) Example: doit | $plot(This is aTitle,X Axis,Y Axis) doit | $plot(stdin) $regions Substitute region definition in specified region format, coordinate system, and coordinate format. The default coordinate system is physical, default coordinate format degrees, and default region format DS9. Arguments may appear in any order, as long as they are separated by ',' and no spaces. 137 If one or more properties are specified, only regions with all of the specified properties will be substituted. Syntax: $regions $regions(<options>) where options are one of the following: regions format property coordinate system sky frame sky format = = = = = [ds9|ciao|saotng|saoimage|pros|xy] [include|exclude|source|background] [image|physical|detector|amplifier|wcs] [fk4|fk5|icrs|galactic|ecliptic] [sexagesimal|degrees] also, the old SAOTNG formats are also supported: $regions_pixels $regions_degrees $regions_hms $include_regions $include_regions_pixels $include_regions_degrees $include_regions_hms $exclude_regions $exclude_regions_pixels $exclude_regions_degrees $exclude_regions_hms Example: dosomething $regions | $text dosomething $regions(pros) | $text dosomething $regions(source,wcs,fk5) | $text dosomething $regions(saotng,background,exclude,ecliptic,sexagesimal) | $text $text Display text in a text dialog window. This macro should be the last macro of a command line. To display text from only STDOUT use '|' as the pipe command. To display text from both STDOUT and STDERR, use '|&' as the pipe command. No parameters are required. The macro is removed from the command line before execution. Syntax: $text Example: doit | $text # stdout doit |& $text # stdout and stderr 138 $url URLs are processed and stored in a temporary file. Only HTTP and anonymous FTP are supported. Syntax: $url(http://<hostname>:<port>/<query>) $url(ftp://<hostname>/<filename>) Example: $url(http://legacy.gsfc.nasa.gov/rosat/data/p000s26b.img.Z) | uncompress | $image $url(ftp://legacy.gsfc.nasa.gov/rosat/data/hri/images/rh100193_img.fits) | $image $vo_method Returns the vo method. Syntax: $vo_method Example: echo '$vo_method' | $text $x $y Substitute coordinates of an bind event. When a bind event is triggered, the x,y coordinates of the mouse of the particular data file are returned. The default coordinate system is physical. This macro is only available for bind commands. Syntax: $x $x(<coordinate system>,<format>) $y $y(<coordinate system>,<format>) where: coordinate system = [image|physical|detector|amplifier|wcs|wcsa...wcsz] sky frame = [fk4|fk5|icrs|galactic|ecliptic] sky format = [hms|sexagesimal|degrees] Example: echo $x(fk5,sexagesimal) $y(fk5,sexagesimal) | $text $xpa 139 Returns the xpa access point name. Syntax: $xpa Example: echo '$xpa' | $text $xpa_method Returns the xpa method. Syntax: $xpa_method Example: echo '$xpa_method' | $text Help The user may define his own HELP message. This message will be available to the user as a menu item. An optional label maybe specified. The default label is Help. When invoked, an text dialog window will appear, containing the message. Multiple HELP items maybe defined within a menu or across hierarchical menus. Example: help Main Help A help message may contain multiple lines of description of the tasks in the menu or menus endhelp Parameters The user may define his own macros or parameters to be evaluated before the command line is executed. To do this, the user defines a param segment that is referenced in the command line. The param definition has the follow format: param <name> <variable> <entry | checkbox | menu> <title> <default> <{comment}> ... endparam or param <name> @<iraf param filename> end 140 The definition either consisted of a number of variables, one per row, or the name of a IRAF style parameter file. DS9 will look for the IRAF parameter file in: ./<filename> $UPARM/<filename> $HOME/iraf/<filename> Example: param foobar var1 entry {Variable 1} default {this is a entry} var2 checkbox {Variable 2} 1 {this is a checkbox} var3 menu {Variable 3} AAA|BBB|CCC {this is a menu} endparam To use parameters, specify the param name at the beginning of your command line: Parameter Test * menu $param(foobar); echo "$var1 $var2 $var3" | $text When the menu item is selected, the user will be presented with a dialog box that contains entry, checkbox, or menu choices for each variable specified. If the user clicks ok, the values are substituted in the command line before execution. Hierarchical Menus The user may define hierarchical menus. Use this to organized crowded menus. To do this, frame menu entries with hmenu <label> and endhmenu. Hierarchical menu labels may contain spaces. Multiple levels maybe implemented. Example: hmenu Stuff hello * menu echo "Hello" | $text world * menu echo "World" | $text hmenu More Stuff hello world * menu 141 echo "Hello World" | $text endhmenu endhmenu Will create an hierarchical menu with two members, hello and world.

Broadly speaking, SAMP is an abstract framework for loosely-coupled, asynchronous, RPC-like and/or event-based communication, based on a central service providing multi-directional publish/subscribe message brokering. The message semantics are extensible and use structured but weakly-typed data. For more information on SAMP, please click here. The samp implementation for DS9 is based on the XPA model with 2 private calls: ds9.get Arguments cmd (string) required url (string) optional Returned value OK (samp.result map) value (string) optional url (string) optional ERROR (samp.error map) samp.errortxt (string) ds9.set Arguments cmd (string) required url (string) optional Returned value OK ERROR (samp.error map) samp.errortxt (string) ds9.set maybe called via notification, call and call/wait. ds9.get can only be called via call and call/wait. Most of the ds9.get calls return a value string, but a few will return a url instead. 2mass about analysis array bin blink catalog cd cmap 148 colorbar console contour crosshair cursor data datacube dsssao dsseso dssstsci exit file first fits frame grid header height iconify iis imexam lock lower magnifier mask match minmax mode nameserver nvss orient pagesetup pan pixeltable plot prefs preserve psprint print quit raise regions rgb rotate saveimage savefits savempeg 149 scale shm single skyview sleep smooth source tcl tile update version view vo wcs web width zscale zoom 2mass Support for 2MASS Digital Sky Survey.

IRAF uses the IIS protocol to communicate with a valid image display server, such as DS9, ximtool, saoimage, and saotng. With DS9, no special scripts are needed. If you have one of the above currently working, DS9 works right out of the box. And DS9 now supports IRAF's new IIS image display protocol that supports up to 16 display frames. All native DS9 functions may be used with images load with IRAF display except for the Scale menu items. Values displayed may the the true values, if a linear scale is specified with the display command. Otherwise, the value is a scaled value. DS9 supports IRAF in all display visuals including Truecolor. Support full postscript printing of images loaded from IRAF is provided. Command Line Arguments As with ximtool, the follow command line arguments may be used to specify the communication parameters: fifo fifo_only inet_only port port_only unix unix_only The default parameters are: fifo /dev/imt1 port 5137 unix /tmp/.IMT%d Configuration An IRAF image server uses a configuration file to specify the number of available buffers and their sizes. What actually passes from IRAF is not the buffer size, but an index number into this file. So when an image server starts (DS9), it will attempt to locate this file as $HOME/.imtoolrc and /usr/local/lib/imtoolrc. If not found, it will look for shell environment variables IMTOOLRC and imtoolrc, that contains the name of the configuration file. If no configuration file is found, DS9 will assume the following default configuration: 201 1 2 512 512 # 2 2 800 800 # 3 2 1024 1024 4 1 1600 1600 5 1 2048 2048 6 1 4096 4096 7 1 8192 8192 8 1 1024 4096 9 2 1144 880 # 10 2 1144 764 ratio 11 2 128 128 # 12 2 256 256 # 13 2 128 1056 14 2 256 1056 15 2 1056 128 16 2 1056 256 17 2 1008 648 18 2 1024 680 19 1 4096 1024 imt1|imt512 imt2|imt800 # imt3|imt1024 # imt4|imt1600 # imt5|imt2048 # imt6|imt4096 # imt7|imt8192 # imt8|imt1x4 imt9|imtfs full screen (1152x900 minus frame) # imt10|imtfs35 full screen at 35mm film aspect imt11|imt128 imt12|imt256 imt13|imttall128 tall imt14|imttall256 tall imt15|imtwide128 wide imt16|imtwide256 wide imt17|imtssy Solitaire imt18|imtssn Solitaire # imt19|imt4x1 # # # # # # & & & & narrow for spectro. wider for spectro. thin for spectro. fatter for spectro. fmt w/ imtool border fmt w/out imtool border If on the other hand, IRAF assumes a different buffer size, the image will appear corrupted and DS9 may issue a number of error messages. Another problem is that this file must be in sync with dev$graphcap. If your system administrator has made changes to graphcap, they must also be implemented in imtoolrc. Here is a note from NOAO: The messages means that there is no /usr/local/lib/imtoolrc file on the machine. This is created as a symlink to dev$imtoolrc by the iraf install script but only if the /usr/local/lib dir already exists on the machine. The fix is the create the dir and rerun the install script or else make the link by hand. Users can also just copy dev$imtoolrc to $HOME/.imtoolrc and restart the server to also workaround it. Note that an existing .imtoolrc might define old frame buffer configs which might confuse things, so if the system file exists check for a private copy screwing things up. Windows DS9 and IRAF To direct image output from IRAF to DS9 running under windows, use the IMTDEV environment variable. For example, if the windows machine is named 'foo.bar.edu', define IMTDEV to the follow value before entering IRAF. 202 $ setenv IMTDEV inet:5137:foo.bar.edu $ cl cl> display dev$pix Scale Menu Disabled When you display an image from IRAF into DS9, IRAF actually does the color scale distribution. In Display, use the ztrans and z1,z2zscale parameter to auto determine z1,z2. Here are the DISPLAY parameters in question: parameters to set the upper/lower bounds and distribution. You can also use the ztrans=[linear|log|none|user] z1=min z2=max zscale=[yes|no] What actually is sent from IRAF to DS9 is one byte per pixel, values 0-200, which already has applied both the upper and lower clipping bounds and the distribution. So this is why, the SCALE menu is disabled in DS9 when it receives a image from IRAF. MSCRED/MSCZERO DS9 now supports IRAF's new IIS image display protocol. However, there is one minor problem with the mscred task msczero. Before using msczero, issue the following command in the cl: cl> set disable_wcs_maps="" cl> flpr IMEXAMINE Due to the unique relationship between DS9 and IRAF, if you use the imexamine task, you can take advantage of a special feature of DS9. Instead of loading the image from IRAF with the display task, load the image directly into DS9. Then, from the cl prompt, invoke imexamine without a filename. IRAF will ask DS9 for the current filename and use it for analysis. This approach provides several advantages over previous methods. First, it will work with compound fits images such as mosaics, data cubes, and rgb images. Second, the image displays includes true image data and WCS information, not the approximated data from IRAF. 203 Regions Regions provide a means for marking particular areas of an image for further analysis. Regions may also be used for presentation purposes. DS9 supports a number of region descriptions, each of which may be edited, moved, rotated, displayed, saved and loaded, via the GUI and XPA. Region Descriptions Region Properties Region File Format Composite Region Template Region External Region Files Region Descriptions Circle Usage: circle x y radius Ellipse Usage: ellipse x y radius radius angle Box Usage: box x y width height angle Polygon Usage: polygon x1 y1 x2 y2 x3 y3 ... Line Usage: line x1 y1 x2 y2 # line=[0|1] [0|1] Vector Usage: vector x1 y1 length angle # vector=[0|1] Text Usage: text x y # text={Your Text Here} text x y {Your Text Here} Ruler Usage: ruler x1 y1 x2 y2 # ruler=[pixels|degrees|arcmin|arcsec] Compass Usage: compass x1 y1 length # compass=<coordinate system> <north label> <east label> [0|1] [0|1] 204 Projection Usage: projection x1 y1 x2 y2 width Projection3d Usage: projection3d x y radius Annulus Usage: annulus x y inner outer n=# annulus x y r1 r2 r3...

Properties are defined for a region in the comment section of description. The exception is the Include/Exclude property. It is set via '+' or '-' preceding the addition, the Line, Point, and Ruler regions have unique properties, not shared by others. Not all are available via the GUI or are applicable for all regions. Text All regions may have text associated with them. Use the text property to set the text. Strings may be quoted with " or ' or {}. For best results, use {}. Example: circle(100,100,20) # text = {This message has both a " and ' in it} Color The color property specifies the color of the region when rendered. The follow 8 colors are supported: Example: circle(100,100,20) # color = green Dash List Sets dashed line parameters. This does not render the region in dashed lines. Example: circle(100,100,20) # dashlist = 8 3 Width Sets the line width used to render the region. Example: circle(100,100,20) # width = 2 Font region is the region region. In properties 206 The font property specifies the font family, size, weight, and slant of any text to be displayed along with the region. Example: circle(100,100,20) # font="times 12 bold italic" Can Select The Select property specifies if the user is allowed to select (hence, edit) the region via the GUI. For Regions used for catalogs and such, it is desirable that the user is unable to edit, move, or delete the region. Example: circle(100,100,20) # select = 1 Can Highlite The Highlite property specifies if the edit handles become visible when the region is selected. Example: circle(100,100,20) # hightlite = 1 Dash Render region using dashed lines using current dashlist value. Example: circle(100,100,20) # dash = 1 Fixed in Size The Fixed in Size property specifies that the region does not change in size as the image magnification factor changes. This allows the user to build complex pointer type regions. Example: circle(100,100,20) # fixed = 1 Can Edit The Edit property specifies if the user is allowed to edit the region via the GUI. Example: circle(100,100,20) # edit = 1 Can Move The Move property specifies if the user is allowed to move the region via the GUI. Example: circle(100,100,20) # move = 1 Can Rotate The Rotate property specifies if the user is allowed to rotate the region via the GUI. Example: circle(100,100,20) # rotate = 1 207 Can Delete The Delete property specifies if the user is allowed to delete the region via the GUI. Example: circle(100,100,20) # delete = 1 Include/Exclude The Include/Exclude properties flags the region with a boolean NOT for later analysis. Use '+' for include (default), '-' for exclude. Example: -circle(100,100,20) Source/Background The Source/Background properties flag the region for use with other analysis applications. The default is source Example: circle(100,100,20) # source circle(200,200,10) # background Tag All regions may have zero or more tags associated with it, which may be used for grouping and searching. Example: Line The line region may be rendered with arrows, one at each end. To indicate arrows, use the line property. A '1' indicates an arrow, '0' indicates no arrow. Example: line(100,100,200,200) # line= 1 1 Ruler The ruler region may display information in 'pixels', 'degrees', 'arcmin', or 'arcsec'. Use the ruler property to indicate which format to display distances in. Example: ruler(100,100,200,200) # ruler=arcmin Point Point regions have an associated type and size. Use the point property to set the point type. Example: point(100,100) # point=diamond 31 Default Properties circle(100,100,20) # tag = {Group 1} tag = {Group 2} 208 The default properties are: text={} color=green font="helvetica 10 normal roman" select=1 edit=1 move=1 delete=1 highlite=1 include=1 fixed=0 Region File Format Syntax Region arguments may be separated with either a comma or space. Optional parentheses may be used a the beginning and end of a description. circle 100 100 10 circle(100 100 10) circle(100,100,10) Comments All lines that begin with # are comments and will be ignored. # This is a comment Delimiter All lines may be delimited with either a new-line or semi-colon. circle 100 100 10 ellipse 200 200 20 40 ; box 300 300 20 40 Header A DS9 region file may start with the following optional header: # Region file format: DS9 version 4.0 Global Properties Global properties affect all regions unless a local property is specified. The global keyword is first, followed by a list of keyword = value pairs. Multiple global property lines may be used within a region file. 209 global color=green font="helvetica 10 normal roman" edit=1 move=1 delete=1 highlite=1 include=1 wcs=wcs Local Properties Local properties start with a # after a region description and only affect the region it is specified with. physical;circle(504,513,20) # color=red text={This is a Circle} Coordinate Systems For each region, it is important to specify the coordinate system used to interpret the region, i.e., to set the context in which the position and size values are interpreted. For this purpose, the following keywords are recognized: PHYSICAL LTM/LTV IMAGE FK4, B1950 FK5, J2000 GALACTIC ECLIPTIC ICRS LINEAR AMPLIFIER using ATM/ATV DETECTOR usingDTM/DTV Mosaic Images While some coordinate systems are unique across mosaic images, others coordinate systems, such as image, or physical , are valid on a per segment basis. In this case, use tile to specify which header to use in all coordinate conversions. The default is the first header, or tile 1. Example: tile 2;fk5;point(100,100) Multiple WCS If an image has multiple wcs's defined, use wcs# to specify which wcs to use for all wcs references. Valid values are wcs, wcsa, wcsb, wcsc... wcsz. Example: wcsa;linear;point(100,100) # point=diamond # pixel coords of original file using # # # # # # # # pixel coords of current file sky coordinate systems sky coordinate systems sky coordinate systems sky coordinate systems currently same as J2000 linear wcs as defined in file mosaic coords of original file # mosaic coords of original file 210 Specifying Positions and Sizes The arguments to region shapes can be floats or integers describing positions and sizes. They can be specified as pure numbers or using explicit formatting directives: position arguments [num] [num]d [num]r [num]p [num]i [num]:[num]:[num] [num]:[num]:[num] [num]h[num]m[num]s [num]d[num]m[num]s size arguments [num] [num]" [num]' [num]d [num]r [num]p [num]i # # # # # # # context-dependent (see below) arc sec arc min degrees radians physical pixels image pixels # # # # # # # # # context-dependent (see below) degrees radians physical pixels image pixels hms for 'odd' position arguments dms for 'even' position arguments explicit hms explicit dms When a "pure number" (i.e. one without a format directive such as 'd' for 'degrees') is specified, its interpretation depends on the context defined by the 'coordsys' keyword. In general, the rule is: All pure numbers have implied units corresponding to the current coordinate system. If no such system is explicitly specified, the default system is implicitly assumed to be PHYSICAL. In practice this means that for IMAGE and PHYSICAL systems, pure numbers are pixels. Otherwise, for all systems other than linear, pure numbers are degrees. For LINEAR systems, pure numbers are in the units of the linear system. This rule covers both positions and sizes. The input values to each shape can be specified in several coordinate systems including: IMAGE LINEAR FK4, B1950 FK5, J2000 GALACTIC ECLIPTIC ICRS PHYSICAL # pixel coords of current file # linear wcs as defined in file # sky coordinate systems # pixel coords of original file using 211 LTM/LTV AMPLIFIER using ATM/ATV DETECTOR using DTM/DTV WCS,WCSA-WCSZ for # mosaic coords of original file # mosaic coords of original file # specify which WCS system to be used # linear and sky coordinate systems If no coordinate system System such as J2000 appear at the beginning new-line or semicolon; is specified, PHYSICAL is assumed. PHYSICAL or a World Coordinate is preferred and most general. The coordinate system specifier should of the region description, on a separate line (in a file), or followed by a e.g., image; circle 100 100 10 physical; ellipse 200 200 10 20 fk5; point 30 50 wcsa; fk4; point 202 47 wcsp; linear; point 100 100 The use of celestial input units automatically implies WORLD coordinates of the reference image. Thus, if the world coordinate system of the reference image is J2000, then circle 10:10:0 20:22:0 3' is equivalent to: j2000; circle 10:10:0 20:22:0 3' Note that by using units as described above, you may mix coordinate systems within a region specifier; e.g., physical; circle 6500 9320 3' Note that, for regions which accept a rotation angle such as: ellipse (x, y, r1, r2, angle) box(x, y, w, h, angle) the angle is relative to the specified coordinate system. In particular, if the region is specified in WCS coordinates, the angle is related to the WCS system, not x/y image coordinate axis. For WCS systems with no rotation, this obviously is not an issue. However, some images do define an implicit rotation (e.g., by using a non-zero CROTA value in the WCS parameters) and for these images, the angle will be relative to the WCS axes. In such case, a region specification such as: 212 fk4;ellipse(22:59:43.985, +58:45:26.92,320", 160", 30) will not, in general, be the same region specified as: physical;ellipse(465, 578, 40, 20, 30) even when positions and sizes match. The angle is relative to WCS axes in the first case, and relative to physical x,y axes in the second. Composite Region A Composite Region is a region which is a collection of other regions, which share common properties. A composite region is composed of a center point and a rotation angle, of which all its members are rendered in reference to. A composite region is defined by the # composite x y angle declaration followed by a number of regions who are or'd together. A composite region is manipulated as a single region within ds9. A composite region maybe created from the current selection of regions by selecting the Create Composite Region menu option. Likewise, a composite region can be dissolved by selecting the Dissolve Composite Region menu option. Template Region A Template Region is a special form of a region which is saved in a special wcs coordinate system WCS0. WCS0 indicates that the ra and dec values are relative to the current WCS location, not absolute. A template region can be loaded at any location into any fits image which contains a valid wcs. For example, a user may create a series of regions, which represent an instrument template. Then, by selecting the Save As Template menu option, a template region saved. The user may now load this templated into any other fits image which contains a valid WCS. External Region Files DS9 can read and write a number of region file formats. Not all formats support all the functionality of DS9 regions. Therefore, the user may loose some information when writing and then reading back from a region file in a format other that DS9. On output, the regions File Format menu or the XPA regions point is used specify the output coordinate system and format. On input, the menu or xpa point is used only for the X Y format. For all other formats, the input coordinate system is specified in the regions file itself.

DS9 currently can not write in this format. POINT is translated into BOX CIRCLE POINT ROTBOX is translated into BOX RECTANGLE is translated into BOX ROTRECTANGLE is translated into a BOX PIE is translated into PANDA The follow regions are not supported ELLIPTANNULUS SECTOR DIAMOND RHOMBUS ROTDIAMOND ROTRHOMBUS XY This format consists of a number of coordinate pairs, one per line. The coordinate format for both input and output is specified via the Save Regions Parameters menu or XPA regions point. The first two coordinates are read, the rest of the line is ignored. The comment character '#' may be used at the beginning of line and the line is ignored. This format is very useful for reading in coordinates from other external analysis programs, such as IRAF. Example: # this is a comment physical # this overrides the specified coordinate system 300 300 400 400 # this is a comment 215 File Formats FITS FITS Image FITS Binary Table FITS Data Cube FITS Multiple Extension Data Cube FITS Multiple Extension Multiple Frames FITS Mosaic FITS Mosaic Data Cube FITS RGB Split FITS Data Array External Format Support External Analysis Support Region Files Color Lookup Table WCS Preference File Startup File TCL FITS DS9 supports FITS images and FITS binary tables. The following algorithm is used to locate and to load the FITS image or table if no additional information is provide: Look for FITS image in primary HDU. If no image is found, examine each extension HDU If image, load If bin table, load if the following is true extension name is EVENTS or STDEVT or RAYEVENT column names X and Y are present If DS9 traverses the entire FITS file without satisfying one of the above, an error is generated. FITS keyword inheritance is supported. All valid FITS BITPIX values are supported, along with -16, for UNSIGNED SHORT. The following FITS keywords are supported: OBJECT BSCALE / BZERO BLANK 216 DATASEC LTV / LTM for physical coords DTV / DTM for detector coords ATV / ATM for amplifier coords WCS keywords WCS# keywords FITS Image At load time, the user may provide just a filename or a filename along with FITS extension name or number. FITS extension names are case insensitive. When specifying an extention, be sure to quote strings correctly to pass both the shell and DS9 parser. Syntax: filename filename[<name>|#] Example: $ds9 foo.fits # default load $ds9 foo.fits[1] # load first extension $ds9 foo.fits[BCKGRD] # load extension named 'BCKGRD' FITS Binary Table At load time, the user may provide just a filename or a filename along with FITS extension name or number, and columns names. FITS extension names and columns names are case insensitive. When specifying a filter, be sure to quote strings correctly to pass both the shell and ds9 parser. Syntax: filename filename[ext] filename[bin] filename[filter] filename[ext][bin] filename[ext][filter] filename[bin][filter] filename[ext][bin][filter] filename[ext, bin] filename[bin, filter] filename[ext, bin, filter] ext [<name> | #] bin=colx,coly # bin counts bin colx,coly # bin counts bin=colx,coly,colz # bin on colz bin colx,coly,colz # bin on colz bin=colz # bin cols 'x', 'y', and colz key=colx,coly binkey=colx,coly 217 (see Introduction to Filtering for more information) Example: $ds9 foo.fits # default load $ds9 foo.fits[1] # load first extension $ds9 foo.fits[BCKGRD] # load extension named 'BCKGRD' $ds9 foo.fits[bin=detx,dety] # bin on detx,dety $ds9 foo.fits[2][bin=rawx,rawy] # load ext 2, cols rawx,rawy $ds9 foo.fits[bg_events,bin=rawx,rawy] # load ext bg_events, cols rawx,rawy $ds9 foo.fits[bin=x,y,pha] # bin on x,y,pi $ds9 foo.fits[bin=pi] # bin on x,y,pi $ds9 'foo.fits[ccd_id==3&&energy>4000]' # quoted filter $ds9 '"foo.fits[ccd_id==3 && energy>4000]"' # double quoted filter $ds9 'foo.fits[events][pha>5,pi<2]' # load extension 'events' and filter The shell environment variable DS9_BINKEY may be used to specify default bin cols for FITS bin tables. Example: $ export DS9_BINKEY='[bin=rawx,rawy]' $ ds9 foo.fits # load FITS bin table, bin on rawx, rawy FITS Data Cube A FITS Data Cube is a FITS image which contains more than 2 axes (NAXES>2). DS9 will automatically detect if a data cube is present and will load all additional images. At the same time, DS9 will display the DataCube dialog box which allows the user to select which 2 image to be displayed. FITS Multiple Extension as Data Cube A FITS Multiple Extension Data Cube file is a FITS file with one or more extensions, that is to be displayed as a data cube. Each image does not have to be the same size, however, only the coordinate systems from the first extension will be used for contours and grids. Example: $ds9 -medatacube foo.fits # load multiple extension fits file as data cube FITS Multiple Extension as Multiple Frames Load a multiple extension FITS file into multiple frames. Please note that files loaded via standard-in or the xpa fits command can not be displayed using this method. Example: $ds9 -multiframe foo.fits # load multiple extension fits file as 218 multiple frames FITS Mosaic A FITS mosaic image may exist as a series of FITS files, or as one FITS file with many extensions. A FITS mosaic may be loaded all a one time, or by the segment. Once loaded, the multiple FITS images are treated as one FITS image. DS9 supports three forms of mosaics: IRAF contains the DETSEC and DETSIZE keywords. See NOAO IRAF Mosaic Data Structures WCS each FITS image contains a valid WCS. HST valid HST WFPC2 data cube, WFPC2 consisting of 4 planes, along with a fits ascii table containing wcs information. Example: $ds9 -mosaicimageiraf foo.fits # load mosaic iraf from one fits file with multiple exts $ds9 -mosaiciraf foo.fits bar.fits wow.fits # load mosaic iraf from 3 files $ds9 -mosaicimagewcs foo.fits # load mosaic wcs from one fits file with multiple exts $ds9 -mosaicimagenext wcs foo.fits # load mosaic wcs from one fits file with multiple exts $ds9 -mosaicwcs foo.fits bar.fits wow.fits # load mosaic wcs from 3 files $ds9 -mosaicimagewfpc2 bar.fits # load wfpc2 mosaic $ds9 -mosaic foo.fits bar.fits wow.fits # load mosaic (iraf or wcs) from 3 files FITS Mosaic Data Cube A FITS Mosaic Data Cube is a FITS mosaic image which contains more than 2 axes (NAXES>2). DS9 will automatically detect if a mosaic data cube is present and will load all additional images. At the same time, DS9 will display the DataCube dialog box which allows the user to select which 2 image to be displayed. FITS RGB 219 A FITS RGB image may exist as three of FITS images, one FITS file with three extensions, or as a FITS 3D Data cube, with three slices, each representing the red, green, and blue channel. A FITS RGB image may be loaded all a one time, or by the channel. Once loaded, the multiple FITS images are treated as one FITS image. Example: $ds9 -rgbimage rgb.fits # load rgb image consisting of one fits file with 3 image exts $ds9 -rgbcube cube.fits # load rgb image consisting of one fits data cube $ds9 -rgb -red foo.fits -green bar.fits -blue wow.fits # rgb image from 3 fits images Split FITS A split fits is a valid fits file in which two files contain the header and data segments. Data Array Raw data arrays are supported. To load an array, the user must providethe dimensions, pixel depth, and optional header size and architecture type. Syntax: filename[options] options are: xdim=value ydim=value zdim=value # default is a depth of 1 dim=value dims=value bitpix=[8|16|-16|32|64|-32|-64] skip=value # must be even, most must be factor of 4 arch=[bigendian|littleendian] Example: $ds9 -array bar.arr[xdim=512,ydim=512,zdim=1,bitpix=16] # load 512x512 short $ds9 -array bar.arr[dim=256,bitpix=-32,skip=4] # load 256x256 float with 4 byte head $ds9 -array bar.arr[dim=512,bitpix=32,arch=littleendian] # load 512x512 long, intel or alternate format: filename[array(<type><dim><:skip><endian>)] type: 220 'b' 's' 'u' 'i' 'l' 'r' 'f' 'd' dim: 8 -bit 16-bit 16-bit 32-bit 64-bit 32-bit 32-bit 64-bit unsigned char short int unsigned short int int int float float float int # x,y dim int.int # x,y dim int.int.int # x,y,z dim skip: int endian: l' little endian 'b' big endian Example: $ds9 -array bar.arr[array(s512)] # load 512x512 short $ds9 -array bar.arr[array(r256:4)] # load 256x256 float with 4 byte head $ds9 -array bar.arr[array(i512l)] # load 512x512 long, intel The shell environment variable DS9_ARRAY may be used to specify default array parameters. Example: $export DS9_ARRAY='[dim=256,bitpix=-32]' $ds9 -array foo.arr # load 256x256 float External File Support DS9 supports external file formats via an ASCII description file. When loading a file into DS9, these descriptions are referenced for instructions for loading the file, based on the file extension. If found, the command is executed and the result, a FITS image or FITS Binary Table, is read into DS9 via stdin. At start-up, DS9 first searches for the ASCII file, named .ds9.filin the local directory, then in the users home directory. # number of bytes to skip 221 The file command first is macro-expanded to fill in user-defined arguments and then is executed externally. The ASCII file that defines the known image files consists of one or more file descriptors, each of which has the following format: Help description A space-separated list of templates A space-separated list of file types (not currently used) The command line for the loading this file type Note that blank lines separate the file descriptions and should not be used as part of a description. Also, the '#' character is a comment character. The following macros are supported: $filename For Example: # File access descriptions: # help explanation # file template # file type # access command IRAF IMH files *.imh IMH i2f -s $filename External Analysis Support For more information about external analysis support files, see Analysis. Region Files DS9 can read and write a number of region file formats. See Regions documentation for more information. DS9 FUNTools Ciao SAOimage IRAF PROS FITS REGION Binary Table XY Color Lookup Table 222 DS9 has a number of default colormaps available to the user. DS9 also supports reading and writing color lookup table formats from the following programs: SAOimage SAOtng XImtool Skycat DS9 uses the file extension to determine the color table format: Ext .lut .lasc .sao any other WCS A new WCS specification can be loaded and used by the current image regardless of the WCS that was contained in the image file. WCS specification can be sent to DS9 as an ASCII file via XPA. The format of the specification is a set of valid FITS keywords that describe a WCS. Example: CRPIX1 CRPIX2 CRVAL1 CRVAL2 CDELT1 CDELT2 CTYPE1 CTYPE2 Format XImtool, SAOtng Skycat DS9, SAOimage DS9 = 257.75 = 258.93 = -201.94541667302 = -47.45444 = -2.1277777E-4 = 2.1277777E-4 = 'RA---TAN' = 'DEC--TAN' Note that the WCS definitions can contain standard FITS 80 character WCS card images, as shown above, or free-form name/value pairs without the intervening "=" sign: CRPIX1 CRPIX2 CRVAL1 CRVAL2 CDELT1 CDELT2 CTYPE1 CTYPE2 257.75 258.93 -201.94541667302 -47.45444 -2.1277777E-4 2.1277777E-4 'RA---TAN' 'DEC--TAN' 223 Preference File A preference file is a valid tcl script generated by DS9 to save the current preference items. See Preferences for more information. Startup File If a startup file ds9.ini is available, it is sourced as the last step in initialization. The following directories are searched in order: ./, $HOME, /usr/local/lib, /opt/local/lib. TCL TCL/TK script file. Users may customize the appearance and enhance the capabilities of DS9 by sourcing their own TCL scripts. 224 Contours DS9 can create and display contours as an overlay on an image. The Display Contours menu is used to display contours. To create, copy, paste, and configure contours, use the Contour Parameters menu. Contour Parameters When creating a new contour, a dialog box appears, in which the user selects the number of contour levels, smoothness, and the distribution of the contours. Contour Levels Specifies the number of contour levels to be generated. A typical number is between 1 and 10. Note: large numbers of contours can take a long time to generate. Contour Smoothness Specifies how smooth the contours are. A smoothness level of 1 will evaluate the contour at each image pixel. A level of 2 will evaluate the contour at every other pixel. The larger the number, the quicker the contour will be generated, and the less detail will be available. Contour Scale Specifies the distribution of the contour levels. A linear distribution will have equal spacing between contours, Log and Ln will be weighted at one end. There are two ways to indicate the contour scale, Use Frame Scale (automatic) and manual Use Frame Scale Use the color scale that the image is currently being displayed in. Therefor there is a one-to-one match between the image color scale distribution and the contour levels. Manual Manually indicate upper and lower levels and a distribution for the contour levels. The contours generated will not be matched to the image color scale distribution. Contour Method There are two methods that are available to calculate the contour lines. The first, BLOCK, blocks down the image, by the smoothness factor, before contours are calculated. As a result, the larger the smoothness, the faster the result. The second method, SMOOTH, smooths the image before calculating contours. As a result, the larger the smoothness, the slower the result. 225 Preferences Allows the user to customize the appearance and behavior of the GUI . Please note: some preferences take effect immediately, while others require DS9 to be restarted. Changes to the preferences can be saved by selecting the Save button. Use the Clear Preferences button to restore default settings. User preferences are stored in .ds9.prf. DO NOT EDIT this file, since it will be deleted or overwritten by DS9. At startup time, DS9 will search for a preferences file in the following directories, in order, ./, $HOME, /usr/local/lib, /opt/local/lib. Users may have several different preference files. DS9 looks for a preference file with its own name. By default, if the application is named ds9, it will look for .ds9.prf. However, if the DS9 application is named foo, then DS9 will look for .foo.prf. In this manner, the user can have several predefined preference files that are activated by invoking DS9 with a different application names. 226 Coordinate Grids DS9 can create and display coordinate grids as an overlay on an image. The Display Coordinate Grid Menu is used to display grids. A coordinate grid is composed of Grid Lines, Axes, Border, and Title. Axes include tick marks, title, and numbers. The appearance of the coordinate grid is specified by parameters. These parameters may be configured via the Coordinate Grid Parameters dialog box. In addition to the axes titles and the grid title, the following menus are available. File Load and Save Coordinate Grid configurations. Coordinate Select the Coordinate system to be displayed. View Toggle the display of Grid lines, Title, Axes, Axes Numbers, and Border. Also specify Interior or Exterior Axes. Color Select the color of Grid lines, Title, Axes, Axes Title, Axes Numbers, Tick marks, and Border. Line Select the line width and style (solid or dash) for the Grid lines, Axes, Tick marks, and Border. Font Select the font family, font style, and font size for the grid Title, Axes Titles, and Axes Numbers. Numeric Formats The user may specify custom numeric formats for either axes. The format specification can be empty (default) or a print function, based on the selected coordinate system: image physical detector amplifier wcs linear wcs equatorial 227 The format specification string to be passed to the C "printf" function (e.g. "%%1.7G") in order to format a single coordinate value. The Format string supplied should contain one or more of the following characters. These may occur in any order, but the following is recommended for clarity: "": Indicates that a plus sign should be prefixed to positive values. By default, no plus sign is used. "z": Indicates that leading zeros should be prefixed to the value so that the first field is of constant width, as would be required in a fixed-width table (leading zeros are always prefixed to any fields that follow). By default, no leading zeros are added. "i": Use the standard ISO field separator (a colon) between fields. This is the default behaviour. "b": Use a blank to separate fields. "l": Use a letter ("h"/"d", "m" or "s" as appropriate) to separate fields. "g": Use a letter and symbols to separate fields ("h"/"d", "m" or "s", etc, as appropriate), but include escape sequences in the formatted value so that the Plot class will draw the separators as small super-scripts. "d": Include a degrees field. Expressing the angle purely in degrees is also the default if none of "h", "m", "s" or "t" are given. "h": Express the angle as a time and include an hours field (where 24 hours correspond to 360 degrees). Expressing the angle purely in hours is also the default if "t" is given without either "m" or "s". "m": Include a minutes field. By default this is not included. "s": Include a seconds field. By default this is not included. This request is ignored if "d" or "h" is given, unless a minutes field is also included. "t": Express the angle as a time (where 24 hours correspond to 360 degrees). This option is ignored if either "d" or "h" is given and is intended for use where the value is to be expressed purely in minutes and/or seconds of time (with no hours field). If "t" is given without "d", "h", "m" or "s" being present, then it is equivalent to "h". ".": Indicates that decimal places are to be given for the final field in the formatted string (whichever field this is). The "." should be followed immediately by an unsigned integer which gives the number of decimal places required, or by an asterisk. If an asterisk is supplied, a default number of decimal places is used which is based on the value of the Digits attribute. All of the above format specifiers are case-insensitive. If several characters make conflicting requests (e.g. if both "i" and "b" appear), then the character occurring last takes precedence, except that "d" and "h" always override "t". The default formats are d.3 for degrees and hms.1 / dms.1 / ldms.1 for sexagesimal. 228 How it Works Table of Contents How DS9 Renders an Image Scales Smoothing Contours Large Files How DS9 renders an image Here is a short description on how DS9 decides to paint a pixel a color on the the screen, give an data value... you need a color scale, a contrast/bias pair for the colorscale, clip values for the data, a scale distribution, and finally, the value of the pixel in question. Step 1. Select a color scale. A color scale is defined as a number of colors (RGB triplets). The number of RGB triplets can vary from just a few to over 200. DS9 contains a number of predefined color scales (Gray, A, B, I8, ...) or the user may load his own color scale. Step 2. Apply a contrast/bias pair. This step takes the result of step 1 and creates a new array with the contrast/bias applied. The length of the new array will between 200 (for pseudocolor) and 4096 (for truecolor). Step 3. Calculate the data clip values (low/high data values). The min/max data values may be used or an algorithm may be used to determine the clip data values. Step 4. Apply the scale distribution. This involves taking the result of step 2, and creating yet another array, this time of size 16384, redistributing the colors, based on the scale algorithm selected (see Scales). Step 5. Based on your data clip values, and the value of the pixel you have, index into the result of step 4, and you have an index into lookup table (for pseudocolor) and an RGB pair (for truecolor and postscript). Scales The log function is defined as the following: 229 as x goes from 0 to 1. The user the colorbar. The default value images as low as 100, and high log function of SAOImage as may specify an exponent a to change the distribution of colors within of a is 1000. Typically, optical images respond well at 1000, IR energy bin tables up to 10000. A value of 10000 closely matches the defined as the following: The pow function is defined as the following: as x goes from 0 to 1. The user may specify an exponent a to change the distribution of colors within the colorbar. The default value of a is 1000. The sqrt scale function is defined as the following: as x goes from 0 to 1. The square scale function is defined as the following: as x goes from 0 to 1. The histogram equalization scale function distributes colors based on the frequency of each data value. Smoothing The user may select one of three types of smoothing kernels. The parameter, r or kernel radius, is defined as the following: Boxcar function, where the width = 2r+1 Tophat function, where the radius = r and the diameter of kernel is 2r+1 Gaussian function, defined as: where the mean = 0 and sigma = r/2, and the diameter of kernel is 2r+1 230 Contours The contour algorithm is from an unknown author and originally came from FV. The difference between the two modes are: block : the image is blocked down before the contour is generated smooth : the image is smoothed via a Gaussian kernel before the contour is generated. block mode is faster as the smoothing parameter increases. Inversely, smooth mode is much slower as the smoothing parameter increases. Large Files There are several factors that determine if DS9 will be able to load a large file. 32 bit OS vs 64 bit OS : to address very large files, you may need to use an 64 bit OS with a 64bit version of DS9. 32bit apps can address up to 4Gb of address space. However, depending on the OS, this limit may be less. Linux for example, the limit appears to be ~3GB (the OS and shared libs eat up a lot of address space). Under 64bit Solaris, 32bit ds9 has a full 4Gb of space. MacOSX appears to have a limit ~3Gb. Under windows, ~2Gb. Large File Support: is the ability to sequence thru files larger than 4Gb. DS9 is compiled with LFS. File system: the OS file system must be able to support files larger than 4Gb. Most recent file systems fully support 4GB>. Memory Management: There are a number of memory management techniques supported in DS9 that will greatly affect the ability and speed of loading large files: $ $ $ $ ds9 foo.fits cat foo.fits xpaset -p ds9 xpaset -p ds9 # uses mmap | ds9 - # allocates memory file foo.fits # uses mmap fits foo.fits # allocates memory Memory Map (mmap) is very fast, limit is memory address space (see above). Allocate is very slow, limit is amount of physical memory + swap partition. Scanning Data: DS9 needs to determine the min and max data values to correctly display your image. For large files, this can take time. You have several options available under the Scale menu: Scan Data - reads all data Sample Data - samples every x values (much faster) Use FITS keyword DATAMIN/MAX or IRAFMIN/MAX - great if in the header, bad because they are always wrong. The best thing to do is to use sample data, and set the data sample between 10 and 100. 231 Backup and Restore DS9 now supports Backup and Restore. When a backup is invoked, DS9 will save in a backup save set all files needed to restore DS9 to that state, including geometry, data files, colormaps, catalogs, contours, and regions. Backup Save Set A backup save set consists of a text file, called a backup script, and an optional directory, which will contain auxiliary data files needed to restore DS9 to a previous state. The backup file and the auxiliary directory maybe moved across file systems, or even platforms, but must remain together in the same directory. Image data files By default, all data image files are save within the backup save set. However, the user has the option, via the Preferences, to only save only an absolute pathname to the data file, and not the data file itself. This option will dramatically reduce the size of a backup save set, but will restrict the usage to a particular file system and platform. Image files that have been loaded into DS9 via XPA, SAMP, or from URL will always be saved into the save set. Caveats There are several caveats in the usage of Backup and Restore. In particular: Currently, there is no support for masks. External Analysis menus will not be saved. Plot Tool windows will not be saved. IIS frames (IRAF) will not be saved. SAMP and XPA sessions will not be saved. In additions, certain complex images which involve multiple load operations will not be saved correctly: Open Mosaic IRAF Segment Open Mosaic WCS Segment Open Multi Ext Data Cube And finally, if the image data had been loaded into DS9 via XPA, SAMP, or from a URL, the following complex load operations are not supported: 232 Open Open Open Open Multi Mosaic IRAF Image Mosaic IRAF Segment Open Mosaic WCS Image Mosaic WCS Segment Open Mosaic WFPC2 Open RGB Fits Image RGB Fits Cube Open RGB Array Open Multi Ext Data Cube Open Ext Multiple Frames 233

SAOImage DS9 Reference Manual

DS9 is the next version of the popular SAOtng display program. It is a Tk/Tcl application which utilizes the SAOtk widget set. It also incorporates the new X Public Access (XPA) mechanism to allow external processes to access and control its data, GUI functions, and algorithms. DS9 supports the direct display of FITS images and binary tables, multiple frame buffers, region cursor manipulation, many scale algorithms and colormaps, and easy communication with external analysis tasks. It is highly configurable and extensible to meet the evolving needs of the astronomical community. DS9 supports advanced features such as multiple frame buffers, mosaic images, tiling, blinking, geometric markers, colormap manipulation, scaling, arbitrary zoom, rotation, pan, and a variety of coordinate systems (including Image, Physical, Detector, and WCS). DS9 also supports FTP and HTTP access. The GUI for DS9 is user configurable.

The Graphical User Interface

DS9s GUI as been designed and implemented for ease of use. It is composed of a menu bar, information panel, panner, magnifier, button control panel, display frames, horizontal and vertical graphs, and a colorbar. The user may reconfigure the display by showing or hiding one or more of the elements. See Preferences for more details. Menu bar File Edit View Frame Bin Zoom Scale Color Region WCS Analysis Help Tear off Menus All DS9 menus can be used as a floating tool palette. To 'tear off' a menu, select the dashed line which is the first item of each menu. At this point, the menu will become its own window, which now can be managed by the user. Mblockquotetiple copies of the same menu can be created. Information Panel The Information panel displays information about the current data values. The information displayed is configurable via the preferences. Panner The Panner allows the user to view the entire frame, along with the current viewing bounding box, image cursor, and wcs cursor. To pan the current frame, click and drag the viewing bounding box. Magnifier The Magnifier displays a magnified view of the current mouse cursor location. The Magnifier cursor outlines the size and orientation of one pixel, given the current frame zoom and orientation.

2

Button Control Panel The Button Control panel provides duplicate menu functionality for ease of use. Frames FITS images are displayed in Frames. Frames may be viewed one at a time, or all at once in Tile mode. Only one frame is the Current Frame, as indicated by the Blue Border, while in Tile mode. Most functions act only on the Current Frame. Graphs Horizontal and Vertical graphs are available to display a cut through the current frame data. While the mouse cursor is in a graph, the information panel reflects the current data values. Graphs are not available while in Tile Mode. Colorbar The Colorbar displays the current colormap and current bias and contrast settings.

Save Image ... Save current image as fits, jpeg, tiff, png, ppm, or mpeg file. Only the visible portion of the image is saved, along with all graphs including regions, catalogs, contours, and grids. If the image is a data cube, saving as a mpeg movie will generate a mpeg-1 movie, one frame per slice of data. Save Frame as Fits... Save the current frame as a fits image. This differs from above in that all image data is saved, not just the visible data. Also, no rotation, zoom, or panning is applied. The main purpose of this feature is to allow a user to load a FITS binary table, and save it as a FITS image. Save Frames as MPEG... Save all frames as a MPEG-1 movie. Each frame is cycled thru and the visible image is saved as one frame of the movie, along with all graphics including regions, catalogs, grids, and contours. Display Fits Header Displays the FITS header. If FITS Mosaic is loaded, a list of headers will be presented.. If FITS Bin Table is loaded, the table header will be displayed, not the binned image. XPA Information Use this menu item to display internal xpa parameters. Open TCL Console Open a TCL console in a separate window. Source TCL Sources a valid TCL file. Print Controls Postscript printing. Destination, PS Level, Color model, and Resolution can be configured. Page Setup Controls Postscript page layout. Orientation and page size can be configured. Exit Quits DS9.

Edit Menu

Undo Allows the user to undo a move, edit or delete action on a region or group of regions. Cut Allows the user to Cut region(s) for later Paste within the same frame or another frame. Copy Allows the user to Copy region(s) for later Paste within the same frame or another frame. Paste If a region or group of regions have been Cut or Copy, this will recreate the regions within the same frame or another frame. Mouse Button Modes DS9 supports a number of modes for configuring the behavior of the mouse when moved, clicked, or dragged over various sections of the DS9 display. None Mode The Mouse Button 1 is disabled. Pointer Mode Information Panel While in Pointer Mode, the information panel displays information concerning the data values under the current mouse cursor location. If the the mouse cursor is not over a valid data value, the information panel will be blank. Graphs If the horizontal or vertical graphs are visible, the data displayed will based on the current mouse cursor location. Again, if the mouse cursor is not over a valid data value, the graphs will show no data.

6

Arrow Keys The arrow keys will move the mouse cursor and all selected regions, one pixel at a time, in the specified direction. Mouse Button 1 Clicking the first mouse button allows the user to select the current frame and select, create, edit, move, and rotate regions. Selecting the current frame If DS9 is in Tile Mode, if you click on a frame that is not the current frame, it becomes the current frame. Use may also use the TAB key to cycle through all frames. Deselecting regions For the current frame, if one or more regions are currently selected, clicking outside of a region will deselect all regions. See Regions for more information. Selecting regions For the current frame, clicking on a region will select that region. SHIFT clicking will toggle the selection of that region to the set of currently selected regions. See Regions for more information. Creating regions For the current frame, if no regions are currently selected, clicking outside of a region will create a new region. See Regions for more information. If you just click and release, circle, rectangle, ellipse, point, and text region can be created in the default size. You can not create a line, ruler, polygon region in this manner. If you click, drag, and release, all region types can be created. After a region is created, it will not be selected. Moving regions For the current frame, a region can be moved by clicking on and dragging. To move multiple regions at the same time, select the regions first, then move. If you click on a non selected region while other regions are selected, the other regions are deselected, and only the clicked region is moved. See Regions for more information. Editing regions

7

For the current frame, a region can be edited (changed in size) by clicking on one of the 4 editing handles, which become visible when a region is selected. See Regions for more information. Rotating regions For the current frame, a region can be rotated by SHIFT clicking on one of the 4 editing handles, which become visible when an region is selected. See Regions for more information. Crosshair Mode While in Crosshair mode, each frame will display a set of crosshairs. To move the crosshairs, click and drag the first mouse button. Information Panel The information panel displays information concerning the data values under the crosshair. Graphs If the horizontal or vertical graphs are visible, the data displayed will based on the current crosshair location. Arrow Keys The arrow keys will move the crosshair in the specified direction, one pixel at a time. Colorbar Mode Change the contrast and bias of the current colormap by click and dragging. This function is also available at all times via the third mouse button. Pan Mode Pan the current image, within the current frame, by click and dragging. This function is also available at all times via the second mouse button. Zoom Mode Zoom the current image, within the current frame. Clicking will zoom by a factor of 2 at the current location. SHIFT clicking will zoom out by a factor of 2 about the center. Rotate Mode Rotate the current image, within the current frame, by click an dragging. Movement to the left will rotate counter clock wise, movement to the right will rotate clock wise. Note: this function is compute intensive, so the refresh rate can be very slow, depending on computer power.

8

Catalog Mode Select / Deselect catalog regions and highlite catalog table entry if available. Examine Mode Creates a new frame and loads the base image into that frame at an increased scale factor in the
same manner as the magnifier. The actual data is not re-loaded, but shared between the frames. Therefor, it

is fast and requires very little additional memory. The user may indicate via the Preferences, if a new frame is created each time or the same frame is used. If the base frame is cleared or deleted, all examine frames will be deleted. It is possible to 'examine' a frame that was created by examine.

Preferences Allows the user to customize the appearance and behavior of the GUI . See Preferences for more information on using and saving preferences.

Frame Parameters Specify Tile, Blink, and display size parameters

12

Bin Menu

To create an image from a FITS Bin Table, the user needs to specify a binning factor, binning buffer size, and the binning function. By default, DS9 will bin about the center of the image. To determine the center of the image, DS9 will look for the following keywords in order: TDMIN/TDMAX TLMIN/TLMAX TALEN AXLEN If no valid keywords are found, DS9 will define the center as the middle of the possible data space based on the coordinate data type. Bin Function Average - all pixel values that fall into one pixel bin are averaged. Sum - all pixel values that fall into one pixel bin are summed. Bin Block In/Out Increase or decrease Bin block factor Bin to Fit Frame Bin to Fit Frame will calculate a bin block factor as a power of 2 that will allow the entire data space to be displayed in the current frame. Bin Block Factor A value greater or equal to zero. This value indicates the number of pixel values that will fall into a particular bin. Bin Buffer Size The overall size of the image generated. This has no relation to min and max values of the columns used to create the image. The image generated is of BIN BUFFER SIZE, centered at the current view center. Binning Parameters

13

Allows the user to specify an arbitrary binning parameters, including filters and 3D binning.

14

Zoom Menu

Use the Zoom Menu to specify the current zoom factor, orientation, and angle of the image in the current frame. Center Frame Will pan to the center of the current frame. For FITS Bin Tables-- The center is defined by the TLMAX, TLMIN, TALEN, or AXLEN FITS keywords if present. If not available, by the min and max of the data type. For FITS Mosaics-- The center is defined bye the DETSIZE FITS keyword. Align to WCS If a valid WCS is present, rotate and orient the image so that the WCS is correctly displayed. Zoom In/Out Zoom in/out the image by a factor of 2. Zoom to Fit Frame Zoom to Fit Frame will calculate the correct zoom factor to allow the entire data space to be displayed in the current frame. Zoom Factor Set current zoom factor. Orientation Set current orientation. Rotation Set current rotation. Pan Zoom Rotate Parameters Invoke a dialog box to specify a view center, zoom factor, and rotation angle for the current frame.

The Scale Menu is used to set the upper and lower limits and the distribution of colors, based on pixel values. Linear Set the colors distribution to Linear. Log Set the colors distribution to Log. Squared Set the colors distribution to Squared. Square Root Set the colors distribution to Square Root. Histogram Equalization Set the colors distribution based on a Histogram Equalization algorithm. MinMax Set the upper and lower limits to the min and max values, or 100%. The image may be scanned to determined these values, based on the Min Max Options. 99.5% to 90% Set the upper and lower limits to based on the specified percentage. A histogram of the data is created and the limits are set to display the percentage, about the mean value. ZScale Set the upper and lower limits base on the IRAF ZScale algorithm. ZScale parameters may be configured via the preference menu. ZMax Set the lower limit base on the IRAF ZScale algorithm and the upper limit on the maximum data value. ZScale parameters may be configured via the preference menu.

16

Scope For FITS Mosaics and Datacubes, scope specifies if the limits are applied global across each FITS Mosaic segment, or on a per segment basis. MinMax Specify how to determine the minimum and maximum values of the image. A selection of AUTO will use SAMPLE for all FITS Mosaics and SCAN for all other files. ZScale Set zscale parameters use DATASEC If the keyword DATASEC is present, and this option is enabled, data not in the bounding box specified by DATASEC will not be imaged, printed, or used in calculations of MinMax and ZScale. The excluded regions are usually bias strips on CCDs and contain no real data. Scale Parameters Invoke a non-modal dialog box to specify Scale Type, Scale Limits, and Scale parameters.

Virtual Observatory Reference

Summary Use the Web proxy connection if your firewall does not allow your computer to connect directly to external computers. In this case, you also must use DS9's internal browser. Details When you click on one of the Virtual Observatory servers in the VO list, DS9 will attempt to connect to that server and (if the internal Web display is enabled) display its Web page. The square box to the left of the server name turns yellow while the connection is being established and then green to signal success. A direct connection is fast and flexible. Among other things, it allows you to perform analysis on your own local data (the VO server will retrieve the image from DS9) and also allows you to use an external browser to load images. Some system managers configure their firewall explicitly to prevent computers in their care from making a direct connection to an external host. Instead, they only allow external access through a Web proxy server (such as SOCKS). If you are using a computer behind a restricted firewall of this sort, then DS9 will not be able to connect directly to a VO server. The yellow box will not turn green and eventually DS9 will display an error message. In this case, you can choose to have DS9 communicate with the VO servers through your Web proxy server. DS9 will use your proxy to send its commands and retrieve its data and analysis results, rather than doing this directly. Note that the following restrictions apply: The transfer of data is slower. You must use the internal Web browser for loading images, etc. You cannot perform analysis on local data. There is a (large but finite) restriction on the number of annuli, and number of polygon points you can specify in a region, as well as the total number of regions allowed. If your computer and firewall have been configured to require use of a Web proxy server, you will have to tell DS9 about this server. Click the Configure Web Proxy button and type the relevant information into the boxes. (Your systems administrator will be able to tell you the details.) At this point, you should be able to connect to a VO server successfully. Please let us know if you have problems!

25

A final note: you may, of course, choose to use the Web proxy even if your computer and firewall are configured to allow direct connections. In this case, there is no need to configure the proxy server.

26

27

Catalogs

DS9 provides full support for loading, displaying, filtering, and saving catalogs. DS9 allows you to overlay symbols from multiple catalogs on the current image. Local and on-line catalog access is supported. Most major catalogs can be retrieved from online servers. Both the CDS and SDSS catalog servers are now supported. Local catalog files in starbase (rdb) or CSV (with or without header) are supported. On-line catalogs are available via services provided by the VizieR catalog access tool, CDS, Strasbourg, France (VizieR is a joint effort of the Centre de DonnИes Astronomiques de Strasbourg and ESA-ESRIN Information Systems Division) and by the Sloan Digital Sky Survey. A selection of popular catalogs is provided in the Analysis menu. In addition, you can search for other catalogs based on title, keywords, mission, wavelength, and object type. When a catalog is overlayed on an image, each displayed catalog symbol consists of a shape, color, and text. An advanced symbol editor is available that allows you to specify the shape, size, color, and text of each symbol, based on catalog column values. These symbol expressions can be saved for future use. Along with the overlay display, a catalog list is provided in a separate window. It displays the column values for each catalog object. The catalog list can be sorted and filtered, and the catalog display will be automatically updated. Advanced filtering options are available. Catalogs can be loaded and saved as local files in ASCII Starbase format. Each catalog contains header information which can be displayed. The list can be printed separately from the image. An interactive connection between the displayed catalog symbols and the catalog list is provided. When you select one or more rows within the catalog list, the corresponding symbols are highlighted on the image display. Conversely, selecting multiple symbols on the image display will highlight the corresponding rows within the catalog list. Catalog symbols can be converted to regions for use with analysis tasks. Filter Option The catalog list can be sorted and filtered, and the catalog display will be automatically updated. A filter is conditional expression, when evaluated for each row of the catalog, if true, the row is displayed, and if false, the row is not displayed. The conditional expression can be any valid TCL expression. The value of a column may be indicated with $. $_RAJ2000>180. && $_RAJ2000<270. $Jmag>11 log($Kmag*10)<.3

28

Advanced Symbol Editor An advanced symbol editor is available that allows you to specify the shape, size, color, and text of each symbol, based on catalog column values. For each row of the catalog, one or more conditional expressions are evaluated. For the first expression to evaluate true, a given symbol is displayed, with the specified shape, color, size and text properties. As with the filter, the value of a particular column can be indicated as $. For the condition entry, the expression you type in is automatically evaluated via TCL expr after macro expansion. 1 0 true false $Jmag>2 sin($Jmag)>.5 [string equal $Class SNR] [regexp {*SNR*} $Class] # # # # # # # # always never always never conditional conditional conditional conditional

For the size, size2, and angle entries, the expression you type in is also automatically evaluated via TCL expr after macro expansion. 2 $Jmag $Jmag/2. (4+2)/3 # # # # value value value value of of of of '2' is column column '2' is used Jmag is used Jmag div 2 is used used

For the text portion, this is not true. It is assumed to be text, unless you explicitly use an expr operator. foo $Jmag symbol (4+2)/3 [expr (4+2)/3] [expr $Jmag/2.] # will put 'foo' above the symbol # will put the value of column Jmag above the # will put the text '(4+2)/3' above the symbol # will put the text '2' above the symbol # will take the value of Jmag and div by 2

And finally, one special case for shape = text and text = empty. In this case, the row number is displayed.

DS9 supports a number of color environments. Not all color environments, or visuals, are available on most machines. In fact, you may be restricted to one or two, base on the color graphics hardware your computer has. A color visual is composed of two parts, the color model and the bit depth. Pseudo color uses a color lookup table to derive the correct color, True color uses the value directly as a RGB triplet, to derive the correct color. The follow is a list of the color visuals DS9 currently supports: pseudo color, true color, 8 true color, 15 true color, 16 true color, 24 8 bit bit bit bit bit

You can use the xdpyinfo command to see if one of these visual are available. NOTE: Linux Users-- if your desired visual is not available, use the Xconfigarator command (Red Hat) or similar command under other versions of linux, to configure your X window visuals. When DS9 is invoked, by default, it will use the default visual. You can find out what the default visual is by using the xdpyinfo command. You can also force DS9 to use another visual by command line option. If you specify a visual, and it is not available, DS9 will exit with an error message. $ds9 $ds9 $ds9 $ds9 $ds9 $ds9 $ds9 $ds9 $ds9 # # # # # # # # # default visual, default depth pseudo color, default depth pseudo color, default depth pseudo color 8 true color, default depth true color, default depth true color 8 true color 16 true color 24

Command Line Options

DS9 will process each command line option, one at a time, as the last step in the initialization process. Therefore, it is possible to use command line options as a little script. For example, the following command line option is used: $ds9 -tile foo.fits -cmap Heat -zscale bar.fits -cmap I8 First DS9 is put in tile mode, then foo.fits is loaded. Then the colormap for foo.fits is changed to Heat and the scale changed to zscale. Next, bar.fits is loaded and the colormap for bar.fits is changed to I8. 2mass about align analysis array bin blink blue catalog cd cmap colorbar console contour crosshair cursor datacube dsssao dsseso dssstsci exit fifo fifo_only file first fits sfits frame geometry green
