Attached below are the results for the OPLEV charge measurement for ETMX and ETMY. The bias voltage for ETMX is between 10-20V (except for one case for Yaw which is around 30V). The bias voltage at ETMY is between 0-10V. The bias voltage measured for both ETMX and ETMY are still not high enough, which would require a sign flipping. 

Once the measurements were complete, all the values were restored.
