coherence around 24Hz in Cal Delta and IMs in yaw, IM4 Trans yaw, and ISS second loop QPD yaw
Unlike the low (but not zero) coherence I found on 3/25, on 3/28 and today, 4/22, there are conferences in the IMs in yaw and Cal Delta of almost 0.4. I added IM4 Trans and ISS Second Loop, and they have conferences with Cal Delta between 0.3 and 0.6. My alog from 3/25 did not find this level of coherence with IMs, alog 47845.
