I took the OPLEV charge measurement for the both the ETMs this morning as they were free. As I started I noted that ETMX had an FPU error (floating point unit), and during the measurement ETMY had lots of overflows, all stemming from H1:FEC-98_DAC_OUTPUT_3_3 (ETMX did not have any overflows).
To center the OPLEVs I had to do the following slider moves
ETMX sliders: P -42.7 to -57.8, Y -147.7 to -131.3
ETMX's charge appears to be increasing and high, its at or above 50V on all quads/DOF.
ETMY sliders: P 140.1 to 170.8, Y -162.8 to -149.0
ETMY's charge seems stable and low, hovering around 0-50 V on all the quads.
After I was finished I restored the sliders and re-misaligned the ETMs as they were when I found them.
