Got called again, this time because the SQZer unlocked and the filter cavity was having trouble relocking. Green could lock fine and it would find IR, but it would unlock before getting to IR_LOCKED. I did the normal thing of adjusting FC2, and later FC1, while trying to maximize H1:SQZ-FC_TRANS_C_LF_OUT, but it didn't help. It seemed like as soon as the gain was changed from 1 to 0 for the H1:SQZ-FC_LSC_DOF1 filter bank during TRANSITION_IR_LOCKING, green would lose lock. Does this make sense or is it just a coincidence?

I tried adjusting the opo temperature just in case, but that didn't seem to help either, at least I don't think it did? It kept going back to just green locked whenever we would get to IR locked. I just realized that we lost lock, and trending back it looks like we lost lock a few minutes before I started adjusting the opo temperature, so that makes sense why the FC guardian was being weird and kept going back to green locked.

Anyway, hopefully that worked, otherwise I'll be back.
