[YamamotoM, NakanoM]

After locking the FPMI only with ETMX without ETMY, the ETMY Q value of 24kHz dramhead mode was measured as 1.70(4)e5.
The attached plots show the ringdown curve. Also, the detail of each measurement is shown in the attached txt file.

The measurement was done for 10 times with the script /users/Commissioning/Q_meas/Qmeas.py. This script switchs the excitation of the TM test, and record the gps time of each switching. Then, make the ringdown curve by processing the AS RF signal.
