Keyword Posn Type Description ------- ---- ---- ----------- OUT 1 CHAR Dataset into which simulated events will be put -> GLOBAL.EVDS (Default event dataset) MODEL - UNIV A background model Default ! FIELDSIZE - REAL The full width of the field in arcmin Default 60.0 PIXSIZE - REAL The quantum for the event lists values Default 1.0 SEED - CHAR The seed for the random number generator. If specified, EVSIM will not poisson deviate the source and background counts. This provides a method of re-creating a previously constructed dataset. Hidden default ! BACK - INTEGER Number of background counts Default ! SOURCEC - INTEGER A list of source counts - separate by spaces or commas. Default ! SOURCEP - REAL A list of source positions - enter x,y consecutively separated by spaces or commas. Default 0,0 PSFCON - LOGICAL Constant psf across field Default YES PSF.. - CHAR The psf to use to generate the data. See under "User Interface" for more information about the psf system. NFILE - INTEGER Number of files to create. Hidden default 1 FFILE - INTEGER Index of first file. Hidden default 1 SRADIUS - INTEGER Half width of psf (in pixels). Default 15 WIDTHS - REAL Width of gaussian for psf. Default 0
