Charge Measurement Update; Pre-ETMX TMDS Use
J. Kissel

First regular charge measurement after O2; last regular charge measurement before the the Test Mass Discharge System (TMDS) tomorrow on ETMX. Trends are consistent with everything that has been true since the July 6th 2017 EQ (I've added by-hand, eye-ball trend lines to guide the eye). The reason I've been wishy-washy on claiming whether there was a jump in effective bias voltage: some quadrants don't show a change after July 6th, others do, and it depends on the suspension. We should really take the time to convert these results into a geometric display of the optic face #between02and03squadgoals. 
 
I won't display the relative actuation strength plots any more, since we don't really care when we're not in an observation run and they don't show much more information than the effective bias voltage plots. If someone still wants to see them, just post a comment to this log with your request.
