(Sheila, Evan, Dan, Kiwamu, Stefan, Alexa)
We were able to lock DRMI + arms off resonance a few times tonight, but the alignment was not great and we would mode hop and lose lock. The guardian is slow to engage the asc wfs, which usually help save the alignment and get the ASAIR build-up high. We need to take a look at our guardian script to get them to engage faster. We did not get a chance to try bringing the offset in and transitioning to TRX+TRY.
The other problem is that DRMI + arms off resonance takes a while to lock (around 20 min), and ALS DIFF is not staying locked for much longer than that. Nic and Sheila worked on a HEPI offloading script (see Nic's alog). However, by the time we got this up and running, ALS DIFF was not locking robustly. For one it seemed we had rung up the bounce mode at 9.8 Hz, which makes locking much more difficult. Another thing we noticed is that the ETMX oplev is glitching.
Of course, as I write this alog, ALS DIFF has been locked for 8 minutes ... unclear what changed.
Nic and Sheila ran Jim's script to run the overnight sensor correction test.
