- The first thing I did this morning was turn on the ISS 3rd loop again, after a measurement. The measurement was taken with the loop open, but a gain of 1 in the filter bank, which used to be the nominal gain. Today I have been using it with a gain of 0.5.
- With the 3rd loop on and the SRM controlled on the dither, I have been using the PR3 spot move state to move the beam on the POP QPD and look for a spot with lower jitter.
- I found a better spot right away, which was not as good as the position we were in when we first came back from the vent.
- I wanted to explore the pop positions in a less random way by scanning the positions on the POP QPD. I got partly through this but had a lockloss and am now running out of time.
- I also ran A2L twice, at two of the extreme positions on the POP QPD.
The second attached screenshot shows some improvement in the DARM spectrum (gold has been our normal spectrum since the spot position move last week, blue is for a different position)
