CAL group
We did the calibration measurements and updated the parameters.

This time we needed to change the fiting limit in parameters_fit.py
Original: m.limits["H_c"] = (self.H_c * 0.95 * 1e-12, self.H_c * 1.05 * 1e-12)
New: m.limits["H_c"] = (self.H_c * 0.90 * 1e-12, self.H_c * 1.10 * 1e-12)

Estimated parameters in the Pre-maintenance measurements are as follows.
 H_etmxtm = 3.831118314e-14 @10Hz ( -0.67% from previous measurements)
 H_etmxim = 1.549324464e-14 @10Hz  ( -3.40% from previous measurements)
 Optical_gain = 2.057370638e+12   ( -0.86% from previous measurements)
 Cavity_pole = 18.205397988 Hz  ( 0.44% from previous measurements)

Previous values are listed in klog#34533.

Estimated parameters in the Post-maintenance measurements are as follows.
 H_etmxtm = 3.845556852e-14 @10Hz ( 0.38% from pre-maintenance measurements)
 H_etmxim = 1.502986128e-14 @10Hz  ( -2.99% from pre-maintenance measurements)
 Optical_gain = 2.043225053e+12   ( -0.69% from pre-maintenance measurements)
 Cavity_pole = 18.072043623 Hz  ( -0.73% from pre-maintenance measurements)
