H1 was out of observing from 14:53 to 15:36 UTC to fix some issues with the SQZ system as we were seeing last night.
After Sheila adjusted the fiber polarization (alog77754), I reverted Corey's changes to the SQZ Guardians' nominal states (listed in his alog77740), then optimized the SQZ angle by running SQZ_MANAGER through 'SCAN_ALIGNMENT_FDS' and 'SCAN_SQZANG,' increasing BNS range by ~10Mpc.
After optimizing the SQZ angle, I accepted SDF diffs for alignment changes of ZM4 and ZM6 (screenshot attached).
