Pushed Updated Cleaning

Jennie, Jenne, Sheila

 

I pushed Jenne's updated cleaning but cannot check if this is better or worse until our problems getting data from nds2 are fixed.

I ran the following:

cd /ligo/gitcommon/NoiseCleaning_O4/Frontend_NonSENS/lho-online-cleaning/Jitter/CoeffFilesToWriteToEPICS/

python3 Jitter_writeEPICS.py

I accepted these DIFFS in OAF model in OBSERVE.snap but we might have to revert them before finish of the commissioning period today if we find out the cleaning is worse.

GPS 139627823 - 16 mins quiet time from last night.

11:12:41 UTC - 11:18:38 UTC quiet time just before cleaning implemented.

11:19:55 UTC new cleaning drops.

11:31:30 UTC end of quiet time.

I took the following jitter comparison measurements

Old Cleaning quiet time: 11:19:55 UTC 0404/2024 light blue

New cleaning quiet time: 13:50:05 UTC 04/04/2024 red

 

Its hard to tell if new cleaning is better and I have reverted the coefficients in OBSERVE.snap to what they were this morning.
