If you read the EDITR help file it tells you that only STOKES='I' is
accepted - all others get you HALF.  But on crowded you can select RR
or LL or both and can also cycle through the IFs.

All standard STOKES handling now goes one place but I guess that UVPLT
and WIPER might wish to have different defaults.
