No problems with green initial alignment, after I touched the optics' sliders to get good flashes.
I was a little unsure about how low the ALS beatnotes are, and it looks like PR3 may have drifted in yaw a teeeny bit according to SUS-PR3_M1_DAMP_Y_INMON over the last few days (well, 0.2 urad which isn't so tiny for PR3), and the green cameras look more clipped than normal (although they were also like that yesterday). So, I did the thing that we "never" do, and touched PR3's yaw slider. It didn't have any obvious beneficial effect, so I immediately put it back.
The rest of initial alignment seems to have gone well while I stepped away. Starting to relock now.
During this round of OMC locking, the pzt scans were getting two sets of our sideband, carrier, sideband "tridents". The current code didn't know how to handle it when it found more than one good place to go. We had a lockloss before I was able to make some smart code, but I quickly threw in a bandaid solution to just choose the second set. This is currenlty running, but I have smarter code ready and tested outside of Guardian that I can load and try on the next lock loss.
OMC locking not going so well. I have stopped ISC_LOCK at PREP_DC_READOUT_TRANSITION.
I set OMC_LOCK to DOWN, changed the ramp time on OMC-PZT2 to 0, then manually found the carrier. I manual-ed OMC_LOCK to OMC_LSC_ON, then requested READY_W_NO_WHITENING. Once it was there, I set ISC_LOCK back to requesting NomLowNoise.
When we achieved low noise, I had to REVERT the OMC-ASC_MASTERGAIN in SDF as Jenne had taken the OMC_LOCK guardian to manual mode and skipped the steps for the automated OMC scan and carrier search. Screenshot attached of the reversion.
