Using Dripta's python script (/ligo/svncommon/CalSVN/aligocalibration/trunk/Projects/PhotonCalibrator/scripts/O4/Pcal_calibration_EPICS.py) to calculate the required EPICS values and write the text file with the caput commands (/ligo/svncommon/CalSVN/aligocalibration/trunk/Projects/PhotonCalibrator/O4_EPICS_calibration/Pcal_LHO_CAPUTfile_O4run_2023-04-25.txt), we updated the EPICS values required by JoeB's new front-end code to calibrate the Pcal power sensor outputs. A copy of the script that generated the .txt, Pcal_calibration_EPICS_2023-04-25.py, is written in the O4_EPICS_calibration directory with the .txt file. Note that it must be run from the scripts directory.
Images of the new PCAL_END_FORCE_COEF.adl MEDM screens are attached below.

The EPICs records,
caput H1:CAL-PCALX_XY_COMPARE_CORR_FACT
caput H1:CAL-PCALY_XY_COMPARE_CORR_FACT
are new to the h1calex and h1caley models as of Tuesday Apr 25 2023 LHO:68959.
As with any new channels added to a front end, one must initialize them within the SDF system in order to accept them to make sure they stick (see instructions on how to do so in, e.g. LHO:67600).
I've initialized these variables and accepted their values as listed above just now (Apr 27 2023 ~19:00 UTC).
