HELP SECTION

XINC
Type: Adverb  (Real)
Use:  The increment associated with an array of numbers.  When used with
      YINC, XINC generally refers to the first coordinate (columns) of
      an image.  It is widely used as an increment in uv data and table
      plotting.
Null value:  0
       Null value assignment generally means 1.
Tasks:
   AHIST.........Task to convert image intensities by adaptive histogram.
                 XINC is the window size in columns.
   ANBPL.........Plots and prints uv data converted to antenna based
                 values.  Every XINC'th data sample is plotted.
   BPPLT.........Plots selected contents of bandpass (BP) files versus
                 time.
   CAPLT.........Plots closure amplitude and model from CC file.  Every
                 XINC'th data sample is plotted.
   CLPLT.........Plots closure phase and model from CC file.  Every
                 XINC'th data sample is plotted.
   DELZN.........Determines residual atmosphere depth at zenith and clock
                 errors.  Every XINC'th data sample is plotted.
   DESCM.........Copies a portion of a UV data set.  Only every XINC'th
                 visibility is copied.
   ELINT.........Determines and removes gain dependence on elevation.
                 Every XINC'th sample is plotted.

                 XINC'th row is exported.
   IMVIM.........Plots one image's values against another's.
   KNTR..........Make a contour/grey plot file from an image w multiple
                 panels.  XINC applies to the polarization vectors.

                 width of rings in arcseconds.
   OTFUV.........Translates on-the-fly single-dish SDD format to AIPS UV
                 file.  Output records are written only every XINC'th
                 time.
   PANEL.........Convert HOLOG output to panel adjustment table.
   PCNTR.........Generate plot file with contours plus polarization
                 vectors.  XINC applies to polarization vectors.

                 every XINC'th sample is printed.
   PRTUV.........Prints contents of a visibility (UV) data set.  Only
                 every XINC'th sample is printed.
