We've had another difficult day for locking, perhaps because it has been windy but there might be something else going on. Here are a few things that we did:
- Changed PRC ALIGN in Initial alignment to use REFL A 9I instead of B for PRX alignment, because it seems like the lock point of B is not correct for yaw, while the lock point of A maximizes the build up.
- offloaded the OM alignment sliders due to last night's move of the AS_A pico
- Yesterday we reduced the IMC UGF back to 35 kHz, because Craig saw that the IMC has been loosing lock on its own (overnight when no one was trying to lock) since we increased the UGF to 85 kHz. I also reduced the gain for ALS COMM this morning to compensate.
- We've had trouble with DRMI acquitision, and RF DARM, and DHARD WFS.
