HELP SECTION

GAINERR
Type:  Adverb (Real array, 30 elements)
Use:   Specifies the estimated RMS gain error (in gain units,
       ie. dimensionless) for each element of an array.
Null Value:  NONE  ( 0 => no gain error)
Tasks:
   CALIB.........Determines antenna calibration: complex gain.  GAINERR
                 is used only with the gain constrained solution type.
   SCIMG.........Full-featured imaging plus self-calibration loop with
                 editing.  GAINERR as in CALIB durinng self-cal steps.
   SCMAP.........Imaging plus self-calibration loop with editing.
                 GAINERR as in CALIB durinng self-cal steps.
   UVFIT.........Fits source models to uv data.  GAINERR are the initial
                 guesses of the antenna gains to be fit.  0 -> no fit.
   UVGIT.........Fits source models to uv data.  GAINERR are the initial
                 guesses of the antenna gains to be fit.  0 -> no fit.
Procedures:
   IMSCAL........Large image self-cal with IM2CC and OOCAL.  GAINERR is
                 passed to CALIB.
   OOCAL.........Determines antenna complex gain with frequency-
                 dependent models.  GAINERR is passed to CALIB.
