Back to OBSERVING
Took H1 back to OBSERVING at 1:22utc (6:22pm). Had an SDF Diff, but it was related to the REFL Servo Gain noted by Thomas & Pep.
Running with a range of ~54Mpc.
Attached is what the SDF Diff was when I ACCEPTED it (but this doesn't match what Thomas notes in his alog).
Here the gain was at 7dB (usually it was 6dB), but Thomas says he changed it vice versa.
