Wait, Wait, Wait. You are moving too fast. Go one by one.
Check the PZTs, the MC, initial pointings, IFO mirrors, some of the partial locks, and maybe some momentary full locks?
Once the recover of the IFO is declared, you can proceed to the measurements.
I hope the grad students can take this precious opportunity to have their fun time for restoring everything by themselves.
I'm leaving the lab now for less than 2 hours. I should be back in time for when the pumping is finished so that I can measure the finesse again.
