Program: IRSET Purpose: Generate a test IRDS Category: IRAS File: irset.c Author: P.R. Roelfsema Description: IRSET allows a user to construct an Infra Red Data Structure (IRDS) within GIPSY for test purposes. This is done by asking the user a series of keywords which specify e.g. the IRAS observing mode, coordinate systems etc. etc. Subsequently the structure is created and dummy data are put into it. Keywords: IRSETOUT= Name of output IR data set [no output] INSTRUME= Instrument name for IR set [ SURVEY B1 ] Can be any combination of SURVEY, SPLINE, AO or FLASH with B1, B2, B3, B4, LRS or BPHF separated by a space. SKYSYS= Custom plate coordinate system [ EQUATORIAL ] EPOCH= Epoch of the coordinate system [ 1983.5 ] CENTER= Custom plate center position in degrees [ 0,0 ] SIZE= Custom plate sizes in degrees [ 1,1 ] OBJECT= Name of object in custom plate [ name of IR set ] OBSERVER= Name of observer [ ??? ] MAXTICKS= Maximum number of satcal ticks [ max number in plate ] NSNIPS= Number of snips wanted in the plate [ 1 ] Subsequently for each snip n ( n running from 0 to NSNIPS-1 ) snip parameters are being asked: SOPn= SOP number for snip n [ n + 30 ] ATTn= ATT number for snip n [ n + 1 ] SCANCALn= Start satcal of original scan of snip n [ n * 3000 ] SCANDURn= Length in satcals of original scan of snip n [ 3000 ] SNIPCALn= Start satcal of snip n [ SCANCALn + 500 ] SNIPDURn= Length in satcals of snip n [ min(MAXTICKS,32) ] PSIn= PSI at begin of snip n [ 0.1 * n radians ] PSIRATEn= PSIRATE at begin of snip n [ 0.00001 radians/tick ] THETAn= THETA at begin of snip n [ 0.05 * n radians ] Updates: Aug 8, 1990: PRR, Document created.
