Finally able to get H1 locked. It is interesting that DRMI was able to lock as soon as Robert was finished turning off his amps and coiling his cables.
Basically made it all the way to NLN automatically.
However, a few issues at NLN:
- Saw a big peak at 20Hz (Robert mentioned he saw this earlier, but it wasn't him---see 1st screenshot)
- SDF Diff due to Excitations---these were a pair of PEM excitations (see 2nd screenshot). Robert killed these, but still had the big peak.
- On Mattermost, RyanS mentioned the 20Hz peak was most likely due to the LOWNOISE_ASC shuffle from earlier today and it was the ADS Lines.
- Jenne noticed this earlier today (see Matt's alog).
- Phoned Daniel since he was next on the Call List (and it was Thurs Dinner). Elenna was able to walk me through how to get rid of this peak (basically taking ADS Clock Gains from 300 down to 0. Remembered seeing this in guardian while troubleshooting....
- Matt made changes to ISC_LOCK.py earlier today, but changes he noted with his initials/date were only related to timers---this is why I didn't notice gain changes. There are comments related to ADS Clock Gains (i.e. "#was 300"), but this was noted from 2020--so I didn't pay attention to them (see 3rd screenshot).
Since Elenna had me zero the clock gains on sitemap/ASC/DitherOverview, I revisited ISC_LOCK.py and changed the 300s to 0s (4th screenshot), SAVED, & hit LOAD, I was kicked out of observing and then I took H1 back to Observing 9-seconds later. (I reckon I should have added a new comment saying I made this gain change and added today's date, but we're already back to observing).
BUT, on the TO DO list is ACCEPTING these CLK GAINS for the next lock. (I've given RyanC (owl) heads up in case this happens overnight.)
