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.
