HELP SECTION

CHINC
Type: Adverb   (Real)
Use:  The number of channels to skip between operations.
Null value:  0
      Null value is usually assigned 1.
Tasks:
   FRING.......Fringe fit data to determine antenna calibration, delay,
               rate.  CHINC gives the channel increment but each CHINC
               channels are averaged.
   IMAGR.......Wide-field and/or wide-frequency Cleaning / imaging
               task.  CHINC is the number of input channels skipped
               between output image planes.
   PLOTC.......Plots color schemes used by 3-color plot tasks.  CHINC is
               used for UVPLT.
   RLDLY.......Fringe fit data to determine antenna R-L delay
               difference.  CHINC gives the channel increment but each
               CHINC channels are averaged.
   SERCH.......Finds line signals in transposed data cube.  CHINC is the
               increment in line widths tested.
   SPLAT.......Applies calibration and splits or assembles selected
               sources.  CHINC is the increment in input channels
               between output channels for one of the averaging modes.
   SPLIT.......Converts multi-source to single-source UV files w
               calibration.  CHINC is the increment in input channels
               between output channels for one of the averaging modes.
   TVFLG.......Interactive flagging of UV data using the TV.
   UFLAG.......Plots and edits data using a uv-plane grid and the TV.
               0 -> NCHAV.
   UVDEC.......Decrements the number of spectral channels, keeping every
               nth  (= CHINC).
   UVHGM.......Plots statistics of uv data files as histogram.
   UVHIM.......Makes image of the histogram on two user-chosen axes.
   UVIMG.......Grid UV data into an "image".
   UVPLT.......Plots data from a UV data base in multiple ways.
               0 -> NCHAV.
   WIPER.......Plots and edits data from a UV data base using the TV.
               0 -> NCHAV.
Procedures:
   LINIMAGE....Build image cube from multi-IF data set.
   MAPPR.......Simplified access to IMAGR.
"Verbs"
   OBITIMAG....Access to OBIT task Imager without self-cal or peeling.
   OBITMAP.....Simplified access to OBIT task Imager,
   OBITPEEL....Access to OBIT task Imager with self-cal and peeling.
   OBITSCAL....Access to OBIT task Imager with self-cal, NOT peeling.
