This task can make a gross number of plots, so test your plan on the TV before making plot files (if you ever make them). The task is designed to let you examine your table as a function of IF. Each panel represents a time interval of SOLINT seconds, with the data averaged over that interval or with each sample plotted (OPCODE='ALTI'). A panel may contain one antenna of all antennas (OPCODE='ALAN') occuring in the interval. 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. INEXT......'SN','TY, 'PC', 'SY', or 'CL' table to be plotted INVERS.....Version number of table to plot, 0=>highest no. SOURCES....Source list. '*' = all; a "-" before a source name means all except ANY source named. QUAL.......Only sources with a source qualifier number in the SU table matching QUAL will be used if QUAL is not -1. TIMERANG...Time range of the data to be plotted. In order: Start day, hour, min. sec, end day, hour, min. sec. Days relative to reference date. If a start and stop time are given and the XAXIS is 1 (time), then all plots will be from the given start time to the given stop time. Otherwise, the X-axis is plotted over the range of X values found in the data. All plots in a given execution will be on the same X scale in any case. STOKES.....The desired Stokes type of the displayed data: 'R' = RCP, 'L' = LCP, 'RL' or 'RRLL' both RCp and LCP 'DIFF' = vector difference between RCP and LCP. Thus, if OPTYPE='AMP', the result will not be zero even when both polarizations have the same amplitude if the phases differ. 'RATO' = ratio between RCP and LCP - done for amplitudes, system and antenna temperatures, and SNRs only. SELBAND....Bandwidth of data to be selected. If more than one IF is present SELBAND is the width of the first IF required. Units = kHz. SELFREQ....Frequency of data to be selected. If more than one IF is present SELFREQ is the frequency of the first IF required. Units = MHz. FREQID.....Frequency identifier to select (you may determine which is applicable from the OPTYPE='SCAN' listing produced by LISTR). If either SELBAND or SELFREQ are set, their values overide that of FREQID. However, setting SELBAND and SELFREQ may result in an ambiguity. In that case, the task will request that you use FREQID. -1 => all, 0 => first SUBARRAY...Limit display to specific subarray. -1 -> all, 0 -> 1. BIF........First IF IF to plot EIF........Last IF to plot. If OPCODE = 'IFDF'/'IFRA' will plot difference/ratio of specified quantity between BIF and EIF. 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). OPTYPE.....Data to be plotted: 'AMP ' = amplitude, 'PHAS' = phase, 'REAL' = real part 'IMAG' = imag part 'DELA' = singleband delay (SN & CL) 'RATE' = rate (SN, CL & PC) 'SNR' = signal/noise (SN & CL) 'GEO' = geometric delay (CL) 'DOPL' = doppler offset (CL) 'TSYS' = sys. temp. (TY) (for VLA is nominal sensitivity) 'TANT' = ant. temp. (TY) (for VLA either back- or front-end system temperature) 'PDIF' = EVLA Gb * (Pon - Poff) (SY) 'PSUM' = EVLA Gb * (Pon + Poff) (SY) 'PGN ' = EVLA post sync-detector gain = Gb (SY) 'PON ' = EVLA Pon (noise tube on) (SY) 'POFF' = EVLA Poff (noise tube off) (SY) 'PSYS' = EVLA PSUM/PDIF/2 * Tcal (=Tsys) (SY) uses values from the CD table ' ' => 'PHAS' OPCODE.....Type of plot: 'ALAN' => will plot the time average of the table values over each SOLINT with all antennas appearing in one plot 'ALTI' => will plot each time point in SOLINT in a single plot with one plot per antenna (followed by the next SOLINT) other => will plot the time average of the table values over each SOLINT with each antenna appearing in a separate plot DO3COL.....> 0 => use 3-color to separate antennas or times in the ALAN and ALTI modes. Color from red to blue is used for antenna or time number 1-N . <= 0 => use line type 4 for all points plotted. BCOUNT.....If INEXT ='PC', and OPTYPE = 'AMP' or 'PHAS' then BCOUNT specifies the phase cal tone number to be plotted. 0 -> 1. SOLINT.....Critical value determining how the task functions. It is the time interval in seconds for each plot or set of plots. Except for OPCODE='ALTI', the table values are averaged over the SOLINT time interval before plotting. For ALTI, the individual data samples in SOLINT are plotted individually in the plot. SYMBOL.....1: Plus sign (default) 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 FACTOR.....Scale plot symbols by FACTOR 0 -> 1. If FACTOR < 0, draw lines between the points and use abs(FACTOR) to scale the points plotted. DOBLANK....> 0 => plot blanked solutions with a symbol of type DOBLANK (see symbol types above). They will be plotted along the lower edge of each plot. NOTE: if DOTV true and GRCHAN 0 and DO3COL <= 0, then the blanked samples will be in the color of graphics channel 3 (pink) and the good samples in the color of graphics channel 4 (blue). DOBLANK > 0 is forced to be different than SYMBOL by adding 1. CUTOFF.....If >= 0, the task will examine the weight column of the table and if the weight <= CUTOFF, the task will not plot that sample. If = 0, will plot all good points; flagged data are not plotted. CUTOFF is ignored for TY and PC tables and OPTYPEs MDEL, ATM, GEO, and CCAL. DOSCAN.....> 0 => plot scan boundaries when there is an NX table and the X axis is time. The boundary is a tick mark when DOSCAN=2 and a full line when DOSCAN=1. <= 0 -> do not plot boundaries. LTYPE......Labelling type, see HELP LTYPE for details: 1 = border, 2 = no ticks, 3 or 7 = standard, 4 or 8 = relative to ref. pixel, 5 or 9 = relative to subimage (BLC, TRC) center, 6 or 10 = pixels. 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. Add n * 100 to alter the metric scaling. 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. ----------------------------------------------------------------
