TITLE: 10/26 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Corrective Maintenance
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY:
PSL is still down, PSL team will be in tomorrow to continue their work.
I just worked on PCAL measurements for Oct.
PCAL:
Neil and I followed the instructions found on Procedure and Log T1500062 to get an End Y ES measurement done.
Beam Spots Looked great: Beam Spot
The Png files for Martel measurement , WS@TX , WS@RX , WS@ RX with Both Beams at the same time all look fine with out any transients of large spikes.
Analysis of ES data:
Anthony.sanchez@cdsws25: python3 generate_measurement_data.py --WS "PS4" --date "2024-10-25"
Reading in config file from python file in scripts
../../../Common/O4PSparams.yaml
PS4 rho, kappa, u_rel on 2024-10-25 corrected to ES temperature 299.7 K :

There was also Lab measurements to pair with this:

https://git.ligo.org/Calibration/pcal/-/tree/master/O4/lab/measurements/t20241025_200318_PS4_PS5_BF?ref_type=heads
I checked out these measurements, added them to a trend to see where they fall next to our previous lab measurements , and used them to run the analysis of the ES data with the Latest PS4/PS5 measurments.
