Measurement was finished at 23deg. I rotated the mirror back to 0deg. There was some discrepancy in measurement at this position. The measurement is ongoing in between 1.34-1.36 and 16.42-24.62 with 1mV resolution for first and second LC respectively.

Measurement finished and could find voltages range where both azimuth and ellipticity are crossing 0.
Then, with help of Yiru Zi-Hao and Byeong-Jun we moved the laser source to ATC clean room.
We did not brought back any replacement source yet.
