INCLASS UV data (class). INSEQ 0.0 9999.0 UV data (seq. #). 0 => high INDISK 0.0 9.0 Disk unit #. 0 => any BAND Q,A,K,U,X,... CALIN Antenna gains file ANTENNAS Antennas to plot 0=>all PIXRANGE Range to plot: 0 => self scale each antenna separately NPLOTS 0.0 28.0 Number of plots per page DO3COL -1.0 1.0 > 0 use 3-color symbols for ALIF, ALST, ALSI OPCODEs and SUM OPTYPE. LTYPE -10.0 10.0 Type of labeling: 1 border, 2 no ticks, 3 - 6 standard, 7 - 10 only tick labels <0 -> no date/time DOTV -1.0 1.0 > 0 Do plot on the TV, else make a plot file GRCHAN 0.0 8.0 Graphics channel ---------------------------------------------------------------- GCPLT Type: Task Use: Plots selected values from gain curve text file Adverbs: INNAME.....UV file name (name). Standard defaults. INCLASS....UV file name (class). Standard defaults. INSEQ......UV file name (seq. #). 0 => highest. INDISK.....Disk unit #. 0 => any. BAND.......Desired band:'4','P','L','S','C','X','U','K','A', or 'Q'. CALIN......The name of a file to provide the antenna gains used to populate the initial CL table. If CALIN is left blank, it defaults to a system file located at: 'AIPSIONS:VLA.GAINS' (old VLA) or 'AIPSIONS:EVLA.GAINS' (EVLA) The file is in free format with fields: a 1-character band code, antenna number, begin date in form YYYYMMDD, end date YYYYMMDD, and 4 gain curve coefficients. The EVLA file adds a column between band and antenna for the frequency in MHz. ANTENNAS...A list of the antennas to be plotted. All 0 => all. If any number is negative then all antennas listed are NOT to be plotted and all others are. PIXRANGE...If PIXR(1) < PIXR(2), all plots will be from PIXR(1) to PIXR(2). Otherwise each plot will be self-scaling. NPLOTS.....Number of antennas to plot per page (try 5). DO3COL.....> 0 => use 3-color to separate frequencies. LTYPE......Labelling type: 1 = border, 2 = no ticks, 3 - 10 = standard, with 7-10 all labels other than tick numbers and axis type are omitted. Less than 0 is the same except that the plot file version number and create time are omitted. DOTV.......> 0 => plot directly on the TV device, otherwise make a plot file for later display on one or more devices (including the TV if desired). GRCHAN.....Graphics channel (1 - 7) to use for line drawing. A value of 0 causes more than one graphics channel to be used. ----------------------------------------------------------------
