We rotated the sample by 90 degrees and fine tuned the rotation angle to minimize p polarization power at the readout.

Results are attached to this entry.

It seems that previous position was better so today we rotated the sample back to this position.

Actually, trying to minimize the p polarization after the sample, we rotated clockwise from injection part by an additional 2.54 deg.

From HWP, it seems that we are now at 0.6 deg from theta = 0 deg.
