QUICK SUMMARY:
While trying to LOCK DRMI
I touched up BS and SRM but I still couldn't get DRMI locked. (likely pecause there was activitiy on the HAMS)
I then started an initial alignment.
I got into SRC align and could not find SR2. I pushed around SR2 to try and find it by hand, but I realized that there was still activity on and near the HAMS duirng the first stages of IA, and I had also potentially caused problems with the IA by requesting the laser stay at 2 watts in the middle of a movement. So I re-requested initial alignment and allowed SRC to do it's thing without intervention.
SR2 sliders are currently -8.6 for P and 2058.8 for Yaw
Reverting SR2 Sliders ONLY to 1401741295 (Last initial Alignment before a lock)
Which were -631.6 in P 282.6 in Yaw
Ended up moving SR2 sliders back, and moving SRM sliders to get better fringes while align IFO was in SRC align.
Jenne Driggers helped me out by pointing me in the right direction with SRM and showing me which thresholds to lower
H1:LSC-SRCL_TRIG_THRESH_ON from 0.006 -> 0.003
H1:LSC-SRCL_TRIG_THRESH_OFF and 0.004 -> 0.002
Once I started to lock and got back up to DRMI the Beam splitter was very off in pitch, which is wild since I just did an initial alignment. While touchingup the beamsplitter alignment, there was a lockloss from DRMI, maybe from my BS movement.
X arm had the PDH issue again which eventually resolved itself.
Currently trying to lock DRMI again.
