The 20220202 195044 It looks like the Lyot filter temperature was about 1 degree low, and for some reason (I forgot what we were testing), temperature compensation was turned off. We should remove 20220202.195044 from future processing. This may need to be epoch-based because it may be hard to come up with a criteria that would cover this issue.

The Lyot filter is also too cool for the next 3 files, but these were rejected for GBU =16 identical temps. We got lucky here since the data would have been poor quality. But there is only one pair of files with identical temps, so I dont understand why 3 files got tagged with Reason 16. I believe 20220202.195251.ucomp.1074.l1.p5.fts and 20220202.195705.ucomp.1074.l1.p5.fts should pass the GBU with reason 0. 20220202.195457.ucomp.1074.l1.p5.fts should still have reason 16 since it matches 20220202.195457

The next group appears to have bad frames during wave data; the new pipeline code should catch the missing states and process them to L1. 20220310 195208, 200822 (both doppler) 20220311 193315 20220313 194616, in doppler 200551, 203925 20220611 194735 20220612 015723, 011047 (doppler)

In 20220902, Lyot filter temps start the morning very low and only appear to come up to temperature about 17:50UT in the unfiltered temps. Unfortunately, the filtered LCVR temps stay low until about 20UT, so most/all of the morning data is probably suspect.

My comment about reason 16, seen above, was based on an incorrect understanding of how we calculated identical temps. I remember it as identical temps between two fits files and not multipole RTD probes measuring the same value.
