We did the calibration measurements and updated the parameters.
Previous values are listed in klog#34597.
Estimated parameters in the Post-maintenance measurements are as follows.
H_etmxtm = 3.826820474e-14 @10Hz ( -0.49% from previous-maintenance measurements)
H_etmxim = 1.551001415e-14 @10Hz ( 3.19% from previous-maintenance measurements)
Optical_gain = 2.013447997e+12 ( -1.46% from previous-maintenance measurements)
Cavity_pole = 18.113567910 Hz ( 0.23% from previous-maintenance measurements)
Fig.1 show the fitting results.
Fig.2 show the ratio of the sensing function
Note: We were not able to perform morning calibration duo to large earthquake.
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#34671 (k1calcs).
- No changes in guardian (Fig.2).
- Changes in SDF tables shown in Fig.3-4 are related to this klog#34670 (k1calcs), and klog#34666 (k1calex, k1caley).
- No changes in the model (Fig.5).
Finally, I raised CFC_LACTCH and IFO guardian moved from CALIB_NOT_READY to READY.
