For seven calibration meeasurements over the last two weeks I captured the thermal state of the interferometer, and used the broadband calibration injection taken at that time, and a 10 minute DARM measurement from a nearby quiet time, to get the calibration corrected DARM plots.
The thermal states were captured using thermal_state_capture.py in labutils.
The data was processed using Run_DARM_calib.ipynb in ligo/jennifer.wright/Documents/thermal_state
The BB injection measurements I used are in: /ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O3/H1/Measurements/FullIFOSensingTFs
The DARM spectra I used for quiet times are in /ligo/home/jennifer.wright/Documents/thermal_state
Calibrated DARM plots are saved in /ligo/gitcommon/labutils/pcal_bb_inj_quick_cal/plots and data is saved in /ligo/gitcommon/labutils/pcal_bb_inj_quick_cal/data

I am going to add post some more DARM measurements from other days as I process them.
I plotted all the DARM spectra scaled by the PCAL BB measurement on the same graph, and corrected the parts where the coherence was low to match the unscaled DARM measurement.
Plot is in /ligo/home/jennifer.wright/Documents/thermal_state/pcal_corrected_darm_2023-04-05_0313UTC-to-2023-04-13_0115UTC.pdf
And code is in /ligo/home/jennifer.wright/Documents/thermal_state/Run_DARM_calib.ipynb.
I updated the code to include GPS reference times for the DARM spectra and some additional measurements which were taken on the 10th, 14th and 20th of April.
Code is in: /ligo/home/jennifer.wright/Documents/thermal_state/Run_DARM_calib_20230424.ipynb
