I dropped H1 out of observing at 02:29 UTC so Sheila and I could try and touch up squeezing to hopefully improve the inspiral range.

We started by scanning the OPO temperature, but to try and stop the filter cavity from unlocking as it had been earlier today, lowered the scan amplitude on line 857 of the SQZ_OPO_LR Guardian from 0.015 to 0.007 and loaded the Guardian. Still, with just a couple seconds left in the scan, the filter cavity unlocked. The temperature didn't look like it needed changing though from the scan we did get, so we set it back to its previous setpoint. Then, we ran a SQZ angle scan with SQZ_MANAGER (after taking SQZ_ANG_ADJUST to 'IDLE') and decided an angle of about 165deg looked good, so we updated the angle servo setpoint on line 53 of sqzparams.py from 0 to -1 and loaded the SQZ_ANG_ADJUST Guardian. We set SQZ_MANAGER to do an alignment scan next, but forgot that the 'SCAN_ALIGNMENT_FDS' state does another angle scan to start. Since that scan ended with the angle in a quite different place that looked worse to us, we just put the angle back to 165 before the alignment scan started. After that, DARM high frequency BLRMs and inspiral range looked slightly better, so H1 resumed observing at 03:09 UTC.
