Last night I worked on the MC incident beam such that we can hit the center of the MC mirrors.
Steve and I checked the incident beam on MC1. We found the beam is ~5mm south.
This was not too critical but it is better to be realigned. I moved the steering mirror on the OMC
table (in vac). We kept the MC resonated. After the maximization of the resonance, I realigned the
MC1 and MC3 such that the resonance in dominated by TEM00.
Jenne, Kiwamu, and I then closed the light door on to the OMC/IMC.
I will make more detailed entry with photos in order to explain what and how I did.
