I took the OPLEV charge measurements for both the ends this morning.

I ran into the same issue as had previously with ETMX constantly saturating no matter what amplitude I used. Jeff suggested I look at the biases and see if they're correct, the biases used for ETMX were [-9, -4, 0, 4, 9] and I changed them to [-8. -4. 0. 4. 8] in ESD_Night_ETMX.py which stopped the overflows. I then had to fine tune the amplitude (too low, bad coherence), through the first measurement, amplitudes of 10000, 12000, and 20000 wasn't enough, I ended up at 100,000 which gave me the best measurement I've seen in month. LR did still have some big error bars, the charge is high on LR, and UR but looks low at UL and LL, and the recent trend actually looks to be decreasing, looking at the year long trend it actually looks fairly stable considering the massive error bars on a lot of the measurements. Every quadrant is under + 100 [V].

ETMY also initially had some saturations but reducing the gain by 20% stopped them and still yielded good coherence. ETMY's charge is slightly high, it's just under + 100 [V] on 2/3 of the quadrants, UR is the only quadrant below +/- 50 [V], it has risen since May, but zooming out to the whole year it doesn't look to have much of a trend, May wasn't a great measurement.
