DOSTOKES
Type:  Adverb     (Logical,  > 0  =>  true)
Use:   Selects options related to polarization such as conversion from
       VLA polarizations to true Stokes parameters or flagging across
       polarizations.
Null value:  false (-1).
Verbs:
   BDF2AIPS......Read EVLA ASDM/BDF data into AIPS.  DOSTOKES specifies
                 the number of Stokes values in the data to be
                 selected.
Tasks:
   DEFLG.........Flags uv data based on decorrelation of the data over
                 time.  DOSTOKES true means to flag all polarizations
                 when one is bad.
   FLAGR.........Flags data based on internal RMS, amplitudes, weights.
                 DOSTOKES controls which Stokes are flagged when a bad
                 point is found.
   SNFLG.........Flags uv data based on jumps in an SN or CL table.
                 DOSTOKES true means to flag all polarizations when one
                 is bad.
