Relocking notes
- Could only get ALS X fiber polarization to 21% (DIAG_MAIN message not cleared)
- ALS for both X and Y arm struggling to stay locked long enough to get through LOCKING_ALS
- Ran through IA just for green arms. After WFS were offloaded, ALS seems much more stable. Perhaps this isn't being done in ISC_LOCK?
- Touched up BS for PRMI lock.
- DRMI not locking. Going for full IA.
- IA complete using IA Guardian.
- Very fast DRMI lock. Good.
- Lockloss at DRMI_LOCKED_CHECK_ASC
- DRMI locked very fast again.
