HELP SECTION

CSCOR
Task:  This task makes a number of corrections to a CS table.
       NOTE: Only data modified are written to the output table.
       If only a subset of the records are to be modified then
       copy the old file to a new copy using TACOP and then run
       CSCOR with GAINVER=GAINUSE.  If all records are to be
       modified; even if several runs of CSCOR are required,
       then GAINVER and GAINUSE may differ.
Adverbs:
  INNAME.....Input UV file name (name).      Standard defaults.
  INCLASS....Input UV file name (class).     Standard defaults.
  INSEQ......Input UV file name (seq. #).    0 => highest.
  INDISK.....Disk drive # of input UV file.  0 => any.
  STOKES.....The desired Stokes type of the output data:
             'R ', 'L ', 'RL', '  '=> 'RL'.
  BIF........First IF to process. 0=>all.
  EIF........Highest IF to process. 0=>all higher than BIF
  TIMERANG...Time range of the data to be used. In order:
             Start day, hour, min. sec,
             end day, hour, min. sec. Days relative to ref.
             date.
  ANTENNAS...A list of the beam numbers to be modified.
             All 0 => use all.
  SUBARRAY...The subarray to modify. Do only one at a time.
  GAINVER....The input CS table version number.
             NOTE: There is NO default value.
  GAINUSE....The output CS table version no. 0 => create new
             table.
  OPCODE.....Operation code (see also EXPLAIN CSCOR):
             'OPAC' => apply atmospheric opacity amplitude
                       corrections using zenith opacity of
                       BPARM(1) nepers.
             'GAIN' => Correct using polynominal gain curve for
                       antenna gain as a function of the zenith
                       angle (ZA) in degrees.
                       correction = BPARM(1) + ZA * BPARM(2) +
                          ZA * ZA * BPARM(3) ...
             'PTRA' => Correct Right ascension *
                       cos(declination) by a polynomial in
                       zenith angle (ZA) in degrees:
                       correction(arcsec) = BPARM(1) +
                          ZA*BPARM(2) + ZA*ZA*BPARM(3)...
                       The correction is added to the old
                       position .
             'PTDC' => Correct declination position by a
                       polynomial in zenith angle (ZA) in
                       degrees:
                       correction(arcsec) = BPARM(1) +
                          ZA*BPARM(2) + ZA*ZA*BPARM(3)...
                       The correction is added to the old
                       position .
  BPARM......Parameters: see above.
  CPARM......CPARM(1) = Antenna longitude in degrees (if no AN file)
             CPARM(2) = Antenna latitude in degrees (if no AN file)
             If there is no antenna file and these are not given, the
             task has to die.
  BADDISK....A list of disks on which scratch files are not to
             be placed.  This will not affect the output file.
