This morning the IFO was down due to PSL issues, hence we got a window of opportunity to take charge measurements on the ETMX and ETMY. Attached below are the results for the same.

ETMY: There is a slight increase in the effective bias voltage for all 3 quadrant for the pitch (breached 50V for the 2nd quadrant). However for the Yaw the bias voltages are within permissible limits and there has been a slight decline.

ETMX: Overall, the bias voltage has been less than 50V, except for the 1st quadrant for the pitch and yaw which are at +50V.
