IM2 (PMMT1) oscillations - time series and power spectrums
IM2 signals changed behavior on 23 Feb around 19:00UTC.
Pitch and Yaw signals sent from about 1 count pp to 6 counts pp.
Looking at OSEM signals, UL and LL decreased in pp counts, UR remained about the same, and LR increased it's pp counts.
Plots attached: power spectrums look very similar to the "good" values, time series shows the OSEMs and the increased pitch and yaw signals.
