I've processed the actuator measurements taken on 0424, and produced new GPR results.

The data files are in ^/trunk/Runs/O3/H1/Measurements/FullIFOActuationTFs/

The script is ^/trunk/Runs/O3/H1/Scripts/Uncertainty/process_allmeas_writeGPRHDF5_20190502.py

I have compared  the MCMC fitting results from the 0424 meas to the MAP values in the 0416 model file. They are very close:

MCMC UIM: Gain = 1.628 (N/A),  model: 1.634, kappaU = 0.996328029375765

MCMC PUM: Gain = 0.02945 (N/A), model: 0.02947, KappaP = 0.9993213437393961

MCMC TST: Gain = 4.417e-11 (N/V**2), model: 4.427e-11, KappaT = 0.9977411339507568

The multi-meas GPR results without kappa correction (first pdf) are not different from the kappa corrected multi-meas GPR results  (second pdf). So I decided not to correct kappas.

The full 4 sets of measurements vs the 0416 model plots are in the third pdf.

That further improves the uncertainty estimate. See the png file. Note: it does not include the 0502 sensing meas (48945)
