[Yokozawa]
I tried to lock the PRFPMI today, but failed. I wrote the memo for lock trial.
1. SAL alignment worked (partially) well.
Xarm/Yarm IR lock with GR were succeeded, PRMI lock succeeded. But IR trans light(X~0.8, Y~0.8) and POP90I RF PD(~0.7) signal were slighly lower than reference.
2. Micro-seismic motion was large
3. We couldn't see the light in the AS gige camera and OMC QPD.
