XYRATIO 0.0 X/Y ratio 0 -> fit TV or 1 PL ---------------------------------------------------------------- BLPLT Type: Task Use: To create one or more plots (on the TV or plot files) of the selected BLCAL (BL) table. The plots will be a set of profiles separated on the vertical axis by an increment in second antenna number one plot per first antenna. Normally, BLCAL is run to have a single solution averaged over all times, but BLPLT will plot multiple times if they are present. All baselines for the first time are plotted followed by all baselines for the second time, and so forth. Both polarizations will appear on each plot if they are present and requested. Adverbs: INNAME.....Input UV file name (name). Standard defaults. INCLASS....Input UV file name (class). Standard defaults. INSEQ......Input UV file name (seq. #). 0 => highest. INDISK.....Disk drive # of input UV file. 0 => any. INVERS.....Specifies the version of the BP, BD, PD, or CP table to be read as input. 0 -> highest. FREQID.....Specifies which freqiency ID to plot. 0 => 1. SUBARRAY...The subarray number to be plotted. 0 => 1. BIF........Lowest IF to be plotted. 0 => 1 EIF........Highest IF to be plotted. 0 => highest. STOKES.....If the first character is R or L then only that polarization is plotted. Otherwise both are plotted if present. TIMERANG...Time to be plotted: start day, hour, min, sec, end day, hour, min, sec. T1 = T2 => plot and average all times. T1 < T2 => average over T1 through T2 and plot T1 through T2; T1 > T2 => average all times but plot only T2 through T1. ANTENNAS...A list of antennas to be included. all 0 => include all If any in the list is negative, then include all antennas except and that appear (in absolute value) in the list. Thus ANTEN = 3,-5,7 includes all antennas except 3, 5, and 7. CODETYPE...'AMP ' to plot the amplitude of the BL values. 'PHAS' to plot the phase of the BL values. 'REAL' to plot the real part of the BL values. 'IMAG' to plot the imaginary part of the BL values. 'DIFA' to plot the amplitude of the vector difference between the current BL values and the average BL values for the selected time and first antenna 'DIFP' to plot the phase of the vector difference between the current BL values and the average BL values for the selected time and first antenna. WARNING: if all the values are similar, then this vector difference phase can have values all over the map. 'DIFR' to plot the real part of the vector difference between the current BL values and the average BL values for the selected time and first antenna 'DIFI' to plot the imaginary part of the vector difference between the current BL values and the average BL values for the selected time and first antenna 'ADIF' to plot the difference in the amplitude of the current BL values and the average BL values for the selected time and first antenna. 'PDIF' to plot the difference in the phase of the current BL values and the phase of the average BL values for the selected time and first antenna. The average BL values is done with a scalar average for amplitudes and a vector average for phases. PIXRANGE...Clip plotted values with PIXRANGE. 0 => self-scale with the max min for all solutions in the plot. If PIXRANGE(2) < PIXRANGE(1), each small plot will be self-scaled within its own plot area. Else all small plots share the same scaling (which is frequently what you will actually want). Note that phase is initially computed in the range -180 to 180 degrees, but will be plotted in the range 0 to 360 if specified as such. In self-scaled phase plots, the plot with the smaller total range of those two possibilities is used. Values > 360 or < -180 are not available. FACTOR.....Controls the plot scale for each profile. DO3COLOR...<= 0 => use a single line drawing color (TYPE 2). =1 => the various BL values drawn are in a range of colors from blue for the first BL values plotted (at the bottom) to red for the last BL values plotted (at the top). Color distinguishes the second antenna. =2 => use color as an additional separator of intensity. The intensity range is assigned colors from blue at the lowest value to red at the highest. Each point on the plot gets the color appropriate to its intensity. These color options allow the drawings to be more crowded and still somewhat distinguishable. 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. 0 => 1. 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. ----------------------------------------------------------------
