As detailed in LHO alog 15511 and SEI alog 645, the BSC chambers would benefit from LLO's "0.43 Hz only" sensor correction filters for X and Y

Jim and Rich had installed the filters previously. I turned them on at ETMX along X and Y. The gains were set to ensure clear subtraction on the CPS channel relative to the ground by a factor of ~10 near 0.43 Hz as seen in the attached plots.
