Jeff K, Lilli S,

After trying all the model/parameter options over the weekend, we could not find a model that matches both the interferometer and understandable physics. See alog 48102, 48083, 48080, 48057

The model file matching what is currently installed in CAL-CS is /aligocalibration/trunk/Runs/O3/H1/params/modelparams_H1_20190401_ER14_095A.py

The sensing parameters were not obtained from measurements in a correct way. And there's a gain factor manually added to tune the 3 stages of actuation, in order to reduce the overall systematic error. (See plot in 48102)

We need to continue investigating the problem offline, but this is the model that can be used in GDS, and it should generate consistent results to CAL-CS.
