STOKES
Type:  Adverb (String*4)
Use:   Specify which Stokes parameters are to be produced or
       operated upon by a process.  Legal values depend on the
       task.  Normally, they include the Stokes parameters:
             I       Q       U       V
       the combinations of Stokes parameters:
             IV      IQU     IQUV
       the individual correlators:
             RR      LL      RL      LR
       and the combinations of correlators:
             'HALF' = RR and LL
             'FULL' = RR, LL, RL, LR
Null value: '    '
       Null value assignment usually means 'I' or all
