The IFO lock broke at 11 am following which charge measurements on the ETMX and ETMY were performed. Results are attached below. For the ETMX the bias voltage is around 20-30 V and the long term trend also looks fine (is not rising too quickly). For the ETMY, the effective bias is within 10-30 V, except for the Yaw in the 2nd quadrant which is around 40V. The long term trend for the 2nd quadrant for the pitch and yaw mode, looks to be slowly rising; the other quadrant looks to be within the permissible limit. 

The slider values for the optical levers were reset to their original position after the measurements were completed. Any SDF differences were removed too.
