SYVSN Type: Task Use: Plots selected calibration data versus time from specified SY or TY (whichever occurs in the input data set) and SN tables. Unlike SNPLT it constructs functions of the measured Psum, Psys, Pdif, Tsys, or Tant and compares them with functions of the SN table phases, delays, or amplitudes. 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. INVERS.....SY/TY table version number of table to plot, 0=>highest no. SNVERS.....SN table 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 'X' = XLP, 'Y' = YLP, 'XY' or 'XXYY' both XLP and YLP 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. 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: default PSYS 'PSYS' = EVLA PSUM/PDIF/2 * Tcal (=Tsys) (SY) uses values from the CD table 'PSUM' = EVLA Gb * (Pon + Poff) (SY) 'PDIF' = EVLA Gb * (Pon - Poff) (SY) 'TSYS' = Tsys values from TY table 'TANT' = Tant values from TY table OPCODE.....Type of SN data plot: 'PHAS' = gain phase in degrees (default) 'AMP ' = gain amplitude 'DELA' = delay in ns APARM......(1,2) Average SY data over this range of IFs: NO DEFAULT (3,6) Subtract mean SY value in 1 or 2 IF ranges: IFs APARM(3) through APARM(4) and APARM(5) through APARM(6). If 0 in APARM(5,6), do only APARM(3,4). If 0 in APARM(3,4), do not subtract the mean. (7) Scale the result by APARM(7). 0 -> 1. (8) 1 => Plot value/mean - 1 rather than value - mean. BPARM......(1,2) Average SN data over this range of IFs: NO DEFAULT (3,6) Subtract mean SN value in 1 or 2 IF ranges: IFs BPARM(3) through BPARM(4) and BPARM(5) through BPARM(6). If 0 in BPARM(5,6), do only BPARM(3,4). If 0 in BPARM(3,4), do not subtract the mean. (7) Scale the result by BPARM(7). 0 -> 1. SAMPTYPE...The type of smoothing used to make the correlation computation: ' ' -> do not do this computation 'BOX ' = boxcar smoothing (default) 'MWF ' = Median window filter 'GAUS' = Gaussian 'EXP ' = Exponential 'LINE' = Linear (1 - abs(t-t0)/sigma) '2PT ' = Two-point '2PTH' = Two-point + "Hanning" CPARM......Parameters for smoothing function to get SN and SY on the same grid of times (or other X axis parameters) Function support full-width width (1) => support time for SY parameter (0 -> 30) (2) => support time for SN parameter (0 -> 30) Added parameter (FWHM) for GAUS, EXP, LINE (6) => smoothing FWHM time for SY parameter (7) => smoothing FWHM time for SN parameter Units are seconds for XAXIS=1 (time), 0.01 degrees for elevation, parallactic angle, and azimuth, and 10s of seconds for hour angle and LST. XINC.......If XAXIS < 0, compute liner correlation coefficients every XINC seconds. 1 < XINC < 25 -> 180; <= 1 -> don't CROWDED....0 -> polarizations appear in separate panels 1 -> polarizations appear in the same panel (use DO3COL = 1 to separate the two) 2 -> the two parameters appear in the same panel (use DO3COL = 1 to separate the two), polarizations are in separate panels. The SY table values are labeled and the SN values are self-scaled. XAXIS......Variable data are to be plotted against. <= 0 => 1 (< 0) Plot also plots with SY on the X axis and SN on the Y axis, one antenna/polarization at a time. NOTE: SAMPTYPE and CPARM must also be specified (1) = Data label time (2) = Antenna elevation (3) = Hour angle (4) = Local Sidereal Time (5) = Parallactic angle (6) = Antenna azimuth Moving sources are supported for XAXIS 2-6 if a PO table is attached. DO3COLOR...DO3COL = 1 tells SYVSN to plot Right or X polarization in pink (graphics plane 3) and Left or Y polarization in cyan (graphics plane 4). DO3COL = 2 tells SYVSN to separate the plotted points with color representing source. The list of source numbers actually occurring in the table, time range, source list, et al. is translated into consecutive integers (in the same order) and then assigned red through dark blue. Thus source numbers 1,2,5,10 become red, yellow, cyan, and blue, resp. no matter what order they appear in the table. 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. 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.
