We did the weekly calibration measurements in JGW-L2314903.

Estimated parameters in the post calibration for the week of May 30th are as follows.
- Actuator efficiency of TM: -3.4804e-14@10Hz (-1.0% change from last week measurements.)
- Actuator efficiency of IM: -1.4305e-14@10Hz (-0.12% change from last week)
- Optical gain: 5.171272e+12 (+1.2% change from last week.)
Measured OLTF is shown in Fig.1, and residual of TF model with above params and measured TF is shown in Fig.2.
These results will be used only for making offline h(t).

Estimated parameters in the pre calibration for the week of Jun 6th are as follows.
- Actuator efficiency of TM: -3.4914e-14@10Hz (-0.63% change from last week measurements.)
- Actuator efficiency of IM: -1.4225e-14@10Hz (-0.68% change from last week.)
- Optical gain: 5.1009e+12 (-0.18% change from last week.)
Measured and residual of OLTF are shown in Fig.3 and Fig.4, respectively.

After the post measurements, we updated the calibration parameters in
- K1:CAL-CS_DARM_ANALOG_ETMX_TM_FM1
- K1:CAL-CS_DARM_ANALOG_ETMX_IM_FM1
- K1:CAL-CS_DARM_ERR_FM1

Finally, transfer function models at calibration frequency were also updated
for the online line tracking.
Updated channels listed in JGW-L2314962 are shown in Fig.5.
