TITLE: 05/25 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Corrective Maintenance
SHIFT SUMMARY: We are still trying to get our comm/diff beatnotes and PR3 alignment understood. Sheila and Ryan S went on table this morning (alog69907) and maximized our beatnotes with our old PR3 position (Yaw slider 148.5). We struggled to get DRMI locked well after that. Sheila noticed that our green qpd offsets and ITM camera offsets were set back to the old values, incorrect values, so they might have not been saved in SDF and then reverted. Sheila and Ryan made a second trip to the table and retouched the alignment with the correct qpd offsets, camera offsets, PR3 settings, and aligned green arms. Trying to lock again but it looks like we need another initial alignment, running that now.
