HELP SECTION

GAINVER
Type: Adverb  (Scalar)
Use:  Standard data selection adverb; used to specify the
      version number of the input gain (CL, CS) table to be
      applied.  If the gain table has been previously smoothed
      then this table should be specified.
Null value:  0 => highest numbered gain table.
Tasks:
   ANCAL......Places antenna-based Tsys and gain corrections in CL
              table.  GAINVER specifies the CL table to be updated.
   APGPS......Apply GPS-derived ionospheric corrections.
   ATMCA......Determines delay/phase gradient from calibrator
              observations.
   BLAPP......Applies baseline-based fringe solutions a la BLAPP.
   CLCAL......Merges and smooths SN tables, applies them to CL tables.
   CLCOR......Applies user-selected corrections to the calibration CL
              table.
   CLSMO......Smooths a calibration CL table.
   CLVLB......Corrects CL table gains for pointing offsets in VLBI
              data.
   CSCOR......Applies specified corrections to CS tables.
   DELZN......Determines residual atmosphere depth at zenith and clock
              errors.
   ELINT......Determines and removes gain dependence on elevation.
   FARAD......Add ionospheric Faraday rotation to CL table.  GAINVER
              specifies the CL table to be updated.
   SOLCL......Adjust gains for solar data according to nominal
              sensitivity.  GAINVER specifies the CL table to update.
   TECOR......Calculate ionospheric delay and Faraday rotation
              corrections.
   VLAMP......Makes ANTAB file for phased VLA used in VLBI
              observations.
   VLANT......Applies VLA/EVLA antenna position corrections from OPs
              files.
Procedures:
   VLACLCAL...Runs CLCAL and prints the results with LISTR.
