After returing to Observing for about 18min post-Saturday-Calibration, noticed that the DARM FOM trace was above reference at high frequency (+ "H1 Live" trace on nuc33 was also above the reference). Consulted the Troubleshooting SQZ wiki, dropped out of Observing, and did the following:
- Ran SCAN_SQZANG_FDS: This made DARM FOM look better (back at reference for high frequency, but it was still higher for the "H1 Live" trace on nuc33).
- Adjusted OPO Temperature: Able to increase H1:SQZ-CLF_REFL_RF6_ABS_OUTPUT a bit (see attached), but still higher for the "H1 Live" trace on nuc33. Then returned to Observing.
These adjustments had H1 out of Observing from 1917-1922utc. It has now been 10min, and it is looking like I have made the range worse (looking like range is ~15Mpc worse). Will give it more time and see how it goes while I grab lunch.
Vicky got back to me on Mattermost. She suggested running another SCAN SQZANG (because of the OPO adjustment). Went out of observing again to do that, and that restored our range. DARM FOM is still better, but H1-Live on nuc33 is still high...it might be a little lower since my first SQZ adjustments. At any rate, back to Observing.
