XYRATIO 0.0 X/Y ratio 0 -> fit TV or 1 PL ---------------------------------------------------------------- BPLOT Type: Task Use: To create one or more plots (on the TV or plot files) of the selected bandpass-like table. The plots will be a set of profiles separated on the vertical axis by an increment in time or antenna number (depending on the sort selected). More than one plot for more than one antenna or more than one time may be generated. Multiple IFs and polarizations will be plotted along the horizontal axis if they are present in the BP table and selected by the adverbs. Bandpass-like tables generated by BLCHN and PCAL may also be displayed. BLCHN tables are much like BP tables and BPLOT functions normally for them. PCAL tables do not have time as a variable. The D terms will appear in a single plot with antenna number as the Y axis. the source polarizations will also appear in a single plot of Q/I and U/I with source number as the vertical axis. Adverbs: USERID.....Input file user number. Ignored 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. INEXT......Type of table: 'BD' from BLCHN, 'PD' from PCAL (antenna D terms), or 'CP' from PCAL (source polarization), else 'BP' is used 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. 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. BCHAN......Lowest channel of a range of channels to be plotted. 0 => 1. ECHAN......Highest channel number to be plotted. 0 => highest. 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. If two Stokes are present, 'I' will plot (R+L)/2 and 'V' will plot (R-L)/2 for BP tables only. 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 inlcudes all antennas except 3, 5, and 7. CODETYPE...'AMP ' to plot the amplitude of the bandpass. 'PHAS' to plot the phase of the bandpass. 'REAL' to plot the real part of the bandpass. 'IMAG' to plot the imaginary part of the bandpass. 'DIFA' to plot the amplitude of the vector difference between the current bandpass and the average bandpass for the selected time or antenna 'DIFP' to plot the phase of the vector difference between the current bandpass and the average bandpass for the selected time or antenna 'DIFR' to plot the real part of the vector difference between the current bandpass and the average bandpass for the selected time or antenna 'DIFI' to plot the imaginary part of the vector difference between the current bandpass and the average bandpass for the selected time or antenna 'ADIF' to plot the difference in the amplitude of the current bandpass and the average bandpass for the selected time or antenna. 'PDIF' to plot the difference in the phase of the current bandpass and the average bandpass for the selected time or antenna. The average bandpass is done with a scalar average for amplitudes and a vector average for phases. SORT.......Sort order for table. If SORT = 'TA', then each plot will show all antennas at a particular time. Otherwise, each plot will show all times for a particular antenna. Ignored for PD and CP tables (PCAL). 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. DO3COL.....<= 0 => use a single line drawing color (TYPE 2). =1 => the various bandpasses drawn are in a range of colors from red to blue. Color distinguishes baseline when SORT='TA' and distinguishes times otherwise. =2 => use color as an additional separator of intensity, each baseline/time will get the same range of color. 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. ----------------------------------------------------------------
