Lab measurements:
NOTES:
PS4 PS5 measurement used for the above measurement were made on 2024-09-23.
The Measurements done in the PCAL LAB today 2024-11-26 were significantly different from the last set of measurements. Due to a drop in the voltage reported in the following plots. 
https://git.ligo.org/Calibration/pcal/-/tree/master/O4/lab/measurements/t20241126_144208_PS4_PS5_FB?ref_type=heads
https://git.ligo.org/Calibration/pcal/-/tree/master/O4/lab/measurements/t20241126_160713_PS4_PS5_BF?ref_type=heads
And I will need review these further before re-running the ES data with these newest measurements.

This maybe due to some changes in the lab. More vetting time is needed.
