Description
This is the longest (and easiest) pole when it comes to improving ViSP L1 data. We now leverage the advantages of having a dual-beam polarimeter to greatly reduce I → QUV cross talk and thus improve spatial residuals.

The combination is now:
avg_I = (beam1_I + beam2_I) / 2
avg_Q = (beam1_Q / beam1_I + beam2_Q / beam2_I) / 2. * avg_I
