HELP SECTION

WTUV
Type:  Adverb  (scalar)
Use:   This adverb specifies the weight to use in calibration solutions
       for uv data lying outside of the range specified by UVRANGE.
Null value: 0
Tasks:
   CALIB.......Determines antenna calibration: complex gain.
   FRCAL.......Faraday rotation self calibration task.
   FRING.......Fringe fit data to determine antenna calibration, delay,
               rate.
   IM2UV.......Converts an image to a visibility data set.  WTUV is the
               weight to assign the sample at u=v=0.
   KRING.......Fringe fit data to determine antenna calibration, delay,
               rate.
   RLDLY.......Fringe fit data to determine antenna R-L delay difference.
   SCIMG.......Full-featured imaging plus self-calibration loop with
               editing.
   SCMAP.......Imaging plus self-calibration loop with editing.
   UVFND.......Prints selected data from UV data set to search for
               problems.  WTUV is the maximum reasonable weight.
   UVHOL.......Prints holography data from a UV data base with
               calibration.  WTUV scales LM ("UV") in case of a scaling
               error in a previous copy.
   UVMOD.......Modify UV database by adding a model incl spectral
               index.  WTUV > 0 causes weights to be set to 1 on
               output.
   UVPRT.......Prints data from a UV data base with calibration.  WTUV
               scales the printed UVW values (0 -> 0.001 = kilo Lambda)
Procedures:
   IMFRING.....Large image delay fitting with IM2CC and OOFRING.
   IMSCAL......Large image self-cal with IM2CC and OOCAL.
   OOCAL.......Determines antenna complex gain with frequency-dependent
               models.
   OOFRING.....Fringe fit data to determine calibration with spectral
               index options.
"Verbs":
   OBITPEEL....Access to OBIT task Imager with self-cal and peeling.
   OBITSCAL....Access to OBIT task Imager with self-cal, NOT peeling.
