1) Wrong measurement file was used for DARM optical gain estimation.
I had used /users/CAL/current/measurements/2025/0630/0920_DARM_OLG.xml in which the measurement was interrupted.
Correct (re-measured) one is /users/CAL/current/measurements/2025/0630/0920_DARM_OLG-1.xml.
I re-analyzed with correct measurement results and H_DARM and 1/H_DARM were updated.
Finally, the difference from previous results is ~3% and a trend of difference will be reported by Hido-kun.
2) Comparison of the actuator efficiency ratio of ETMX and ITMX was done in wrong configuration.
I had compared A_ETMX_TM/A_ITMX_TM(3) in this time and A_ETMX_TM/A_ITMX_TM(0) in the previous measurement.
So I re-evaluated the difference by using A_ETMX_TM/A_ITMX_TM(3) in the previous measurement.
And also comparison between YPcal and XPcal was added in the table.
