I think RLDIF is ignoring the alias point at 180 deg when averaging
results to derive CLCORPRM. I have a case where all the values are either
above 160 or below -145 (all but one below -165). The CLCORPRM value for
this IF is 46. In a quick attempt to reproduce the average, I have not
gotten that value, but I suspect that RLDIF is weighting by the errors, or
some such, which I haven't done. The unweighted averages, if the alias
point is ignored, is 35 for Ampscalar, 63 for upper data and 87 for lower
data. The actual average should be near 180 (or -180). I can provide
data if needed, but it should be pretty obvious in the code if this is
happening.
Cheers,
Craig
