[Shalika, Marc]

The recent temperature fluctuations led to multiples changes in beam path(tilted), height and input polarization. The mirrors were tuned to make the beam follow one line and at a uniform height of 75 mm all along the table.

The HWP and QWP were tuned to input a polarization of 0°±0.01°(azimuth) and 0°±0.01°(ellipticity)

The input polarizer was then tuned to get 0°±0.02°(azimuth) and 0°±0.02°(ellipticity). The power after the polarizer was 0.832 mW.
