I am attempting to use POSSM's 'POLPLOT' option, but it does not appear to be doing what I expect.I have a spectral line source with strong circular polarization. The first attachment shows RR overplotted with LL. But if I then set POLPLOT='RR/LL', the ratio appears to be a constant, modulo a few noise spikes that occur in channels with no line emission (attachment 2). Indeed, the resulting plot is identical to the one I get if I specify POLPLOT='RR/RL'(attachment 3).Thank you,Lynn
