SYCOP
Task:  SYCOP moves the calibration in AIPS SY and CD extention tables
       from one or more IFs to other IFs.  SY table values are easily
       made useless by RFI, so it may be wise to move values from good
       spectral windows to those so affected.  The output table will
       be a new file.

       NOTE: if you average IFs using more than one in APARM, the
       average is done in the recorded parameters Pdif, Psum, Pgain,
       and Tcal.  However, TYAPL applies them in ratios: Tcal/Pdif for
       gains and Tcal * Psum / Pdif for weights.  Averaging should
       really be done in these parameters in TYAPL rather than by
       SYCOP.  TYAPL does NOT offer this option at present.
Adverbs:
  INNAME.....Input image name (name).       Standard defaults.
  INCLASS....Input image name (class).      Standard defaults.
  INSEQ......Input image name (seq. #).     0 => 1.
  INDISK.....Disk drive # of input image.   0 => any.
  INEXT......Extention table type (e.g. 'CL') ' ' => 'SN'
  INVERS.....Version number of table to copy, 0=>highest no.
             Output version is highest + 1.
  APARM......List of IFs to average (first zero stops list)
  BPARM......List of IFs to receive the average value
