Comment to Optics change on PCI table for birefringence (Click here to view original report: 4022)

After moving the mirrors, I had to realign the beam. The alignment was tuned to obtain horizontal  and vertical  to be within 0.027deg and -0.016deg. See the plot 1 and 2 showing the horizontal  and vertical alignment.
