[Sheila, Jeff, Elenna, Corey]

Today we relocked with some issues. We think that the soft close of the gate valves shook the ITM green cameras enough that the green references were no longer good, which caused many alignment problems through carm offset reduction.

The SRC ASC is OFF in DRMI ASC at this time, by having the use_DRMI_ASC['SRC1'/'SRC2'] flag set to False. When locking, SRM and SR2 might need to be moved by hand before offloading DRMI ASC.

Sheila will write a more detailed alog about the process of updating the green references, because we think we have a better method now. For the summary, we have updated the green camera references, SDFed them in safe, and run an initial alignment after the lockloss.

Other guardian changes:

• DARM OFFSET now occurs after DRMI TO POP and befor PREP ASC FOR FULL IFO. This is how it used to be before the OFI problems. We had some problems with SRC1 P during full IFO engagement, but the problems seemed to go away as soon as we went through DARM OFFSET
• CLOSE BEAM DIVERTERS is now out of the ladder. While we troubleshoot, we want these open, and to avoid lockloss they are closed at 2 W. I removed them from the ladder completely for now.

Tony, Oli and I have been watching violin mode damping. So far, there doesn't seem to be any problems.

By eye, Jeff and I think the PCAL X crosses do not match the line height in CAL DELTA L, so there may be some calibration mismatch. I will run a cal measurement when we are thermalized.

Squeezer is not working, Daniel and others are trying to troubleshoot now.
