Adverbs: INNAME.....file name to hold plots (name). Standard defaults. INCLASS....file name (class). Standard defaults. INSEQ......file name (seq. #). 0 => highest. INDISK.....Disk unit #. 0 => any. TIMERANG...Time range of the data to be fit. In order: Start day, hour, min. sec, End day, hour, min. sec Days relative to reference date. all 0 -> 0,24hour ANTENNAS...A list of the antennas to fit. APARM......Control parameters (1) start MJAD to include 0 -> 0 (2) end MJAD to include 0 -> large (3,4) Limit to elevation range (min,max) 0 -> 7, 122 (degrees) (5) Minimum amplitude 0 => 0.01 (6) Maximum wind speed 0 -> 5 m/sec (7,8) Limit to normalized beamwidth range (min,max) 0 -> 0.95,1.15 (9) Filtered change file gets a line when the absolute value of the change > APARM(9) (0 -> 0.1) (10) and the abs (change) * APARM(10) * sigma (parameter) (0 -> 3.0) BAND.......Restrict to band code ' ' => 'X' Allowed codes P, L, S, C, X, U, K, A, Q FPARM......If FPARM(i) > 0, then fit for the parameter (1) Tilt (2) Azzero (3) Elzero (4) Colima (5) Sag (6) Az3 (7) Azcntr (8) Elcntr (9) Axsprp (10) Az2 (11) Refrac All 0 => fit 1, 2, 3, 4, 11 (12) > 0 -> attach tilt to antenna, else to pad (16) > 0 -> suppress output of gnuplot file (gnuplot made obsolete by AIPS plots) (17) > 0 -> suppress output of ant.dat files If (16) <= 0, (17) is forced to 0 (18) > 0 -> suppress output of changes file May only want to keep the filtered changes file. (19) > 0 -> suppress output of filtered changes file PRTLEV.....Print level used for debugging problems. 0 normal. ASDMFILE...Use both ASDMF(1) and ASDMF(2) to specify the full path to the .PNT file (but leave off the .PNT which the task will append). This could be the same values for ASDMF as used by BDFLIST and BDF2AIPS if you put the .PNT file in the same directory as the top directory of the SDM/BDF files. DOPLOT.....> 0 => make AIPS plot files of the pointing errors before and after fit. DOTV.......> 0 => make the plot(s) on the TV, else make plot files. XYRATIO....Scale the X axis longer than the Y by XYRATIO. If DOTV > 0, 0 -> fit to the TV window If DOTV <= 0, 0 -> 1. DPARM......(1) Symbol type for measured Az and El errors Default is 2, the choices are 1: Plus sign 12: Five pointed star 2: Cross (X) 13: Star of David 3: Circle 14: Seven-pointed star 4: Box 15: Eight-pointed star 5: Triangle 16: Nine-pointed star 6: Diamond 17: Ten-pointed star 7: Pentagon 18: 11-pointed star 8: Hexagon 19: 12-pointed star 9: Septagon 20: 13-pointed star 10: Octagon 21: 14-pointed star 11: Nine-gon 22: Plus with gap 23: vertical line 24: Cross with gap (2) Symbol type for residual Az and El (measured - fit) Default is 3 from choices above (3) Scaling factor for measured Az and El points: Default = 1 (4) Scaling factor for residual Az and El points: Default = 1 (5) Graphics channel for measured Az and El errors. Default is 2, choices are 1 yellow, 2 green, 3 pink, and 4 cyan (6) Graphics channel for residual Az and El; default is 3. ----------------------------------------------------------------
