detuning change for the measurement of FDS during more than one hour

Eleonora and Yuhang

We fixed the CC2 demodulation phase and measure FDS during more than one hour.

During these measurement, filter cavity got unlock twice. Also, for the last measurement, we misaligned filter cavity yaw.

The detuning was stable within ~10min. Even without unlock, detuning changes and unlock almost doesn't change detuning if green is recovered. But detuning will change after a bit misalignment.

Thank you for the measurement.

Can you add the fitting result of homodyne angle?
