In 31DEC19 I have cleaned up the code that decideswhat to do with POLPLT. Among other things it willnow tell you about POLPLOT values that are notrecognized such as RR/RL. It will now support XXand YY and real Stokes as claimed by the help file.I was a bit confused comparing RR/LL with LL/RRsince the ratios are not linear but the plot is. So 1/2looks less impressive than 2.0. Also the timeaveraging can be confusing. I ended up plotting 1baseline at one time and then I believed the values.Tomorrow's MNJ will get what I think is mostly a minor fix.Eric
