PLRFI Task: This task reads the output of VBRFI or VLBRF to make plots (which VBRFI and VLBRF could have made in the first place). Up to 100 such output files may be concatenated, however. If GRCHAN = 0, the first plot for each antenna is a plot of the mean autocorrelation in green, mean rms/mean in blue, and mean rms in pink. The next three plots are the mean autocorrelation, the mean rms, and the mean rms/mean. Pink is the maximum, green the mean, and blue the minimum over scans and polarizations. 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. ANTENNAS...A list of the antennas to be included. All 0 => all. If any number is negative then all antennas listed are NOT included and all others are. BIF........First IF to include. 0 -> 1. EIF........Last IF to include. 0 -> max. BCHAN......First channel to include. 0=>all. ECHAN......Highest channel to include. 0=>all higher than BCHAN SMOOTH.....Specifies the type of spectral smoothing to be applied to a uv database . The default is not to apply any smoothing. SMOOTH=0 IS RECOMMENDED IN VBRFI. VBPLT will allow later smoothing if desired from plots although the results will differ especially for the rms/mean spectra. The elements of SMOOTH are as follows: SMOOTH(1) = type of smoothing to apply: 0 => no smoothing To smooth before applying bandpass calibration 1 => Hanning, 2 => Gaussian, 3 => Boxcar, 4 => Sinc To smooth after applying bandpass calibration 5 => Hanning, 6 => Gaussian, 7 => Boxcar, 8 => Sinc SMOOTH(2) = the "diameter" of the function, i.e. width between first nulls of Hanning triangle and sinc function, FWHM of Gaussian, width of Boxcar. Defaults (if < 0.1) are 4, 2, 2 and 3 channels for SMOOTH(1) = 1 - 4 and 5 - 8, resp. SMOOTH(3) = the diameter over which the convolving function has value - in channels. Defaults: 1,3,1,4 times SMOOTH(2) used when input SMOOTH(3) < net SMOOTH(2). INFILE.....Text file with detailed RFI report. The task initially tries to open the file as named. If that fails, then it appends a BCOUNT to the name and tries again. NOTE: if ECOUNT > BCOUNT, then this form of naming is required. BCOUNT.....Multiple files may be read if they are named INFILE with an integer appended from BCOUNT to ECOUNT. It is a good idea to have the files be in increasing frequency order, but is not required (i.e. there is likely to be overlap on occasion). 0 -> 1. ECOUNT.....Highest file number. < BCOUNT -> BCOUNT. PIXRANGE...Range of values in plot of mean. <0 -> min to max Actually PIXR(2) <= PIXR(1) causes the plot to do the full range of values if PIXR(2) < 0. PIXR(2) = 0 causes the plot to scale to omit up to 5 percent of the samples. This often makes the plot show the remaining points much better. The number of points in each IF that is omitted is plotted (twice) in each IF panel and printed. APARM......If APARM(2) > APARM(1), use this range when plotting the standard deviation. APARM(2) = 0 is like PIXR(2) = 0 to compress the plot range by omitting at most 5 percent of the points. If APARM(4) > APARM(3), use this range when plotting the standard deviation. APARM(4) = 0 is like PIXR(2) = 0 to compress the plot range by omitting at most 5 percent of the points. If APARM(5) > 0, the X axis is labeled with spectral channels rather than frequency. If APARM(6) > 0, omit the first plot (all 3) If APARM(7) > 0, omit the second plot (mean) If APARM(8) > 0, omit the third plot (rms) If APARM(9) > 0, omit the fourth plot (rms/mean) APARM(10) is a mask to exclude the mean (1), min (2), and/or max (4) curves. Thus APARM(10)=6 excludes both max and min curves. DOIFS......> 0 => do not separate IFs, do full X axis label FACTOR.....>= 0 -> Plot data with connected lines < 0 -> Scale plotted points by abs(FACTOR). 0 -> 1.0 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). 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. GRCHAN.....> 0 -> use a specific graphics channel 0 -> use different colors for max (pink), mean (green), and min (cyan) where the colors listed are the defaults for graphics channels 3, 2, and 4, resp. NPLOTS.....Number of plots / page (1 - 9). XYRATIO....X to Y plot scale. 0 -> TV if DOTV true, 1.4 plot files. BADDISK....The disk numbers to avoid for scratch files (sorting tables mostly).
