CLCOP
Task:  CLCOP moves the calibration in an AIPS CL or SN extention table
       from one polarization to the other .  The specified output
       table should not exist before the execution of CLCOP.

       It can convert a one polarization table into a two polarization
       table.  It calls that R2L and forces it to happen.
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.
  OPTYPE.....'R2L'  => copy right hand to left hand, right unchanged
             'L2R'  => copy left hand to right hand, left unchanged
             'SWIT' => copy left to right and right to left - thus
                       switching the polarizations
----------------------------------------------------------------
CLCOP
Task:  Calibration copy to polarization

In some cases a source will allow calibration in only one polarization
- e.g. self-cal using a maser line.  This will allow that calibration
to be copied to the other polarization.
