ANTWT
Type: Adverb  (Real array * 30)
Use:  ANTWT is an array of up to 30 values to be used as
      antenna based, multiplicative corrections to the uv data
      weights to be applied internally in calibration routines.
Null Value: 0 * 30 => 1.0
Tasks:
   BLAPP.........Applies baseline-based fringe solutions a la BLAPP.
   BPASS.........Computes spectral bandpass correction table.
   CALIB.........Determines antenna calibration: complex gain.
   CPASS.........Computes polynomial spectral bandpass correction table.
   FRCAL.........Faraday rotation self calibration task.
   FRING.........Fringe fit data to determine antenna calibration,
                 delay, rate.
   KRING.........Fringe fit data to determine antenna calibration,
                 delay, rate.
   SCIMG.........Full-featured imaging plus self-calibration loop with
                 editing.
   SCMAP.........Imaging plus self-calibration loop with editing.
   WTMOD.........Modifies weights in a UV data set.  ANTWT not zero
                 replaces the weights with ANTWT.
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.
