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.
   ALBUS.........Calculate ionospheric delay and Faraday rotation using
                 ALBUS.
   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.
   DFCOR.........Applies user-selected corrections to the calibration CL
                 table.
   ELINT.........Determines and removes gain dependence on elevation.
   FARAD.........Add ionospheric Faraday rotation to CL table.  GAINVER
                 specifies the CL table to be updated.
   RIFRM.........Task to modify a CL and TE table with IFRM values from
                 ALBUS files.
   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.
