Received a call from Niko.

EY problem -> Wait for Dave till the morning.

Corner station problems need to be worked on now. Niko called Jason and Peter King to ask how to reset PMC HV supply.

In the mean time Niko told me that he couldn't move some of the optics state to ALIGNED. That was mostly becaue of DC centering loops and SQZ ASC were outputting huge numbers, so I just disabled ASC (didn't have to do that for SQZ ASC) and cleared the history.

MC2 length output was big because the MC board boost was on when not in lock. I disabled it to prevent MC2 from tripping. Hopefully the guardian will take care of the rest of the MC board setting once PSL comes back and when Niko runs the down script. If Niko cannot lock IMC he'll call me again.
