Parameters

This section documents the parameters recognized by this task (if any).

Parameter	Mand	Type	Default	Constraints
srclisttab	yes	table	srclist.ds:SRCLIST
The name of the FITS dataset+table which contains the input source list. If the colon + table name is not given, the first table in the dataset is used.
racolumn	no	string	RA
The name of the column from which to read the Right Ascensions of the sources.
deccolumn	no	string	DEC
The name of the column from which to read the Declinations of the sources.
radecunits	no	string	decimaldeg	decimaldeg|hdms|radians
The unit to employ when reading racolumn and deccolumn. NOTE that hdms (ie hh:mm:ss etc) is not yet supported.
expression	no	string	`'
Source selection expression, possibly involving column names, keyword values or constants. See selectlib for the grammar. Only those sources for which the expression evaluates to TRUE are plotted. The default (an empty string) is TRUE for all sources.
withncut	no	boolean	no
Switch which specifies whether the source list (after filtering with expression) should be truncated at some maximum number, specified by parameter ncut.
ncutsortexpression	yes	string	RATE
If a truncation of the size of the source list is desired (ie if withncut=yes), the list must first be sorted according to some criterion. The task evaluates ncutsortexpression and sorts the sources in decreasing order of the result. The parameter ncut is then read and only the first ncut sources (in their sorted order) are plotted.
ncut	no	integer	30	$0\le$ncut
Maximum number of sources to plot. This parameter has no effect when withncut=no.
radiusexpression	yes	string	RATE
This parameter specifies an arithmetical expression, possibly involving column names, keyword values or constants. The result is used to scale the radii of the plotted circles.
radiusstyle	no	string	raw	auto|raw
The radii of the source circles are taken from the result of the expression supplied to parameter radiusexpression; but this result can either be used directly (radiusstyle=`raw', the default) or the value may be processed in an `intelligent' manner by the task (radiusstyle=`auto'). The `auto' routine attempts to choose the extrema and distribution of the circle radii so as to give a visually pleasing result.
withlabels	no	boolean	no
Switch which specifies whether labels should be added to the output.
labelstyle	no	string	expr	sortedint|expr
This parameter is read by the task if withlabels=`yes' and controls how source labels are assigned. See the description of this parameter in subsection 3.6 but, briefly: if labelstyle=`expr', the task uses the values generated by evaluation of the column expression supplied to labelexpression directly as label text; for labelstyle=`sortedint', the labels are constrained to be a sequence of positive integers, assigned according to the setting of the parameter labelsortstyle.
labelsortstyle	no	string	expr	radius|expr|rownumber
This parameter controls how integer-sequence source labels are assigned - that is, it is read by the task only if labelstyle=`sortedint'. See the description of this parameter in subsection 3.6 but, briefly: if labelsortstyle = `expr', the task evaluates sortexpression and assigns the (integer-valued) labels in decreasing order of the result; if labelsortstyle = `radius', the integers increase with decreasing source circle radius; whereas if labelsortstyle = `rownumber', the sequence of integers merely reflects the row number of the source entry in the (filtered, not original) source list.
sortexpression	yes	string	ML_ID_SRC
This parameter is active only if labelstyle = `sortedint' and labelsortstyle = `expr'. In this case the task evaluates sortexpression and assigns the (integer-valued) labels in decreasing order of the result.
labelexpression	yes	string	ML_ID_SRC
This parameter is active if labelstyle = `expr'. Eventually the task will be able to accept in this parameter an expression involving several numeric-valued columns, evaluate the expression, and set source labels from the result; however at present it cannot do this: you can only supply names of single columns from the source list. String-valued columns are also allowed in this case.
colour	no	string	green
Colour of the plotted circle + label. Available colours are black|white|red|green|blue|cyan|purple|yellow.
shape	no	string	circle
Shape of the plotted region. Available shapes are circle|box|diamond|ellipse|boxcircle.
outputstyle	no	string	ds9	ds9|gaia
This parameter controls the output format. At present only ds9 or gaia formats are available. Note that this parameter is not case-sensitive.
extragaiacolumns	no	string list	RADEC_ERR RATE
This contains a list of extra column names to be copied to the gaia output file. It is of course only read if outputstyle=`gaia'.
outfilestyle	no	string	prefix	prefix|whole
The user has the facility to supply just a file prefix (outfilestyle=`prefix'), in which case the post-period suffix is set to `reg' for ds9 files and `gaia' for gaia files, or to supply the full file name (outfilestyle=`whole').
outfileprefix	no	string	region
Prefix of the output file name. This is followed by a period and the suffix `reg' or `gaia' for outputstyle=`ds9' or `gaia' respectively. This parameter is read if outfilestyle=`prefix'.
outfile	no	string	region.txt
The complete output file name. This parameter is read if outfilestyle=`whole'.
