Next: External Functions Up: Fitting of Data Previous: The Corrected Gauss--Newton . ... Basic functions are either defined in the system or defined by the user as external FORTRAN routines. ... Basic functions are specified by the name, the independent variable(s) and parameter(s), with optional guesses for the parameters, following the syntax: name(var1[, ];par1[, ]) [par1=value] . ... Parameters are defined by unique names after the semicolon in the function specification. ...

... All the parameters provided in this database have been obtained using the the MIRIAD ( Sault et al. 1995 ) task MBSPECT . MBSPECT makes a spectrum of the velocity (or frequency) axis of a cube. The spectrum is beam-weighted, over the width specified, for the other image axes. ... Robust parameters are calculated by using an algorithm which minimises the mean absolute deviation of the flux-weighted velocities. mask= This specifies the x-axis ranges to be excluded from any continuum fit. ...

... For an input list of EBOXDETECT source locations, simultaneous maximum likelihood PSF fits to the source count distribution are performed in all energy bands of each EPIC telescope. A description of the main properties of the detection algorithm may be found in Cruddace, Hasinger, Schmitt (1988). ... Note, that =1 in the case of the individual energy band detection likelihoods listed in source table rows with ID_BAND 0 and is equal to the total number of energy bands in the ID_BAND=0 summary rows. ...

Next: Star Formation Rate and Up: No Title Previous: Calculation of Evolutionary Tracks . To start calculations, we choose the distributions of the initial binary parameters: the mass of the primary ZAMS component, , binary mass ratio, , orbital separation a . ... whereas the mass ratio distribution is not. ... The zero assumption often made is that the mass ratio distribution has a flat shape, that is binaries with a high mass ratio occur as frequently as those with equal masses. ...

... Chapter 8: Pointings and Patterns > 8.3 How to Fill Out the Pattern Parameters Form . ... In this case, instead of taking the exposures at each point of the first pattern, the entire Sub-Pattern (or Secondary_Pattern in the Text Proposal File ) will be executed at each point, creating a two-dimensional matrix of pointing offsets. ... Pattern_Type: STIS-MAMA-BOX . ... Pattern parameters that are determined by the pattern type, or have default values, need not (or cannot) be changed in the form. ...

Region markers can be moved, resized, rotated, zoomed, deleted, and can change geometric type. ... For example, markers placed on astronomical catalog positions should be fixed so that one cannot accidentally move them off the specified position. ... Parameters can be fixed using the fix option of the regions public access point (for fixing classes of markers) or by means of a fix keyword in the definition of an externally loaded marker. ... In the command: echo "regions fix all -position -size" | ...

... Each document which is or can be circulated outside DMD division has to be issued according to the following Technical Archive procedure. ... Identify the type of document according to the ESO Documentation Type definition list . ... Get the chronological four-digit number from Technical Archive (pday@eso.org phone 6462 or tecarch@eso.org), specifying: the document type, PSC, document title, author(s), issue and issue date. ... ESO document number (i.e. VLT-SPE-ESO-19100-1836). ... issue number . ...

tranback -- Transform an X,Y position from output to input pixel position using the same conventions as drizzle tranback xout yout . xout = 400 [real] . ... The X dimension of the input image (this is used to determine the centre which is the origin of the transformations). (nyin = 800) [real] . ... If "output" the input image center is mapped to the center of the output grid, rotated about that center and then shifted along the grid of the output image. ...

Tasks in GIPSY are the application programs which do useful work for the user. ... To start a task without parameters, only the name of the task needs to be supplied. taskname To specify parameters, any number of keyword-value pairs separated by blanks can be added to the taskname: taskname keyword1 = value1 keyword2 = value2 .. ... The user can set a parameter in the task context to change requests for hidden keywords into requests for defaulted keywords. ... Tasks all run in a context . ...
