After moving another -28 urad on PR3 yaw in afternoon, I ran CalcSpotPos.py one more time to check the beam position on PR2.

So currently, PR2 Y2L gain is now -6.21, resulting in alpha as -0.29638 (see alog 31402) and the spot position at -12.507 mm.
(-14.904 mm -> -13.595 mm -> -12.507 mm)

Two screenshots are included, showing that we accepted SDFs from the measurement (SAFE, OBSERVE).
