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.
   EXTAB.........Exports AIPS table data as tab-separated text.  Every
                 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.
   LISTR.........Prints contents of UV data sets and assoc. calibration
                 tables.  Only every XINC'th line is listed,

                 software.  XINC applies to MF extension file version
                 numbers.
   MODVF.........Task to create a warped velocity field.  XINC is the
                 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.

                 file.  Only every XINC'th component is printed.
   PRTIM.........Prints image intensities from an MA catalog entry.
   PRTOF.........Prints on-line flag table information.  Only every
                 XINC'th row is printed.
   PRTSD.........Prints contents of AIPS single-dish data sets.  Only
                 every XINC'th sample is printed.
   PRTUV.........Prints contents of a visibility (UV) data set.  Only
                 every XINC'th sample is printed.
   RMSD..........Calculate rms for each pixel using data in a box around
                 the pixel.  The rms is recomputed every XINC'th pixels.
   SMOTH.........Task to smooth a subimage from upto a 7-dim. image.
   SNBLP.........Plots selected contents of SN or CL files on a baseline
                 basis.  Every XINC'th sample is plotted.
