OPLEV charge measurement for ETMY

RyanC, Rahul

We ran the OPLEV charge measurement script for ETMY today during the maintenance and the latest plot is attached below. Due to insufficient time we took only 4 data before truncating the measurement. The effective bias voltage has not changed much from the last measurement. However Yaw (2nd quadrant) has slightly gone up from 30V to 50V and Pitch (3rd quadrant) has also increased from +2V to -16V.

Later in the evening today Austin will run the FAMIS task and post comparison plot between OPLEV and inlock charge measurement results.
