Weekly calibration on 8/8
CAL group
We did the calibration measurements and updated the parameters.

Previous values are listed in klog#34777.

Estimated parameters in the previous measurements are as follows.
 H_etmxtm = 3.855511943e-14 @10Hz ( 0.65% from previous measurements)
 H_etmxim = 1.489006529e-14 @10Hz  ( 0.31% from previous measurements)
 Optical_gain = 1.935046702e+12   ( -1.35% from previous measurements)
 Cavity_pole = 18.118449097 Hz  ( -0.09% from previous measurements)

Fig.1 show the fitting results.

I updated line tracking parameters (JGW-L2314962).

All detected changes are coming from the planned commissioning activities.
- Changes in foton Fig.1 are related to klog#34798 (k1calcs).
- Changes in guardian shown in Fig.2 are related to klog#34791
- Changes in SDF tables shown in Fig.3-4 are related to klog#34797 (k1calcs) and klog#34795 (k1calex, k1caley).
- No changes in the model (Fig.5).

Finally, I raised CFC_LACTCH and IFO guardian moved from CALIB_NOT_READY to READY.
