JimW HugoP, (Friday Oct 24th)

Fabrice recently pointed out that ETMY-ISI was not performing as well as the other LHO BSC-ISIs.

Jim adjusted his LV3 contollers and we tried them on Friday. Only the Y controller was changed. We looked at the logitudinal motion on ST1 of the ISI, and at the Pitch and Yaw motion seen by the (re-calibrated) oplev. We compared the ASDs, and RMS motions, before and after the adjutments.

Attached plots tend to indicate that Jim's controller adjustement helped reducing the ETMY logitudinal RMS motion. The new controllers were left ON on Friday.
