[daip] TST/TVFLG on Stokes RLLR seems to load RR or LL when displaying IF 2

[Michael Rupen]

Dear DAIP,

   TVFLG when run in TST with Stokes 'RLLR' seems to display RR and LL
instead of RL and LR when showing IF 2.  I base this on seeing much
higher amplitudes and consistent phases in IF 2, while seeing much
lower amplitudes and random phases for the phase calibrator in IF 1.
Further, TVFLG with STOKES '' gives very similar or identical results
to TVFLG with STOKES 'RLLR' for IF 2.

   IF 1 looks fine.

   TVFLG with identical inputs in NEW (modulo the new adverbs in TST of
course) is fine.

To set these inputs in either NEW or TST:

default TVFLG
   inname '20080125' ; incla 'C band' ; inseq 1; indisk 1
   docal -1 ; gainuse 3 ; flagver 1 ; nplot 9 ; bparm 0 17 0 ; doarray 1
   docat -1 ; outfgver flagver
   blver -1
   dparm 0 ; dparm(6) 3.3333333 ; dparm(3) 1; STOKES 'RLLR'
   calcode '*'

After doing this I have the following in TST:
