The polarizers were retested today after #015 was redone by Alastair and the silicon had some time to cure. I remeasured the offset of all the polarizer windows, where ↑ is right side up for the label and ↓ is upside down with the label. Nominal height is 4" but it looks like there was a slight upward angle from the mirror.

The requirement is 7 mrad so all of the new polarizer windows look good.
