ITM Optical Levers
KiwamuI, ThomasV
We aligned ITMX and ITMY optical levers to the position of the test masses at approximately 2013-12-16 12:00 PT. We may need to adjust the alignment if the pointing changes due to commissioning activities.

ITMX was reflecting off the compensation plate in the previous ALOG, we had shifted the alignment when trying to put the enclosure back on so we re-aligned receive the first bounce off the HR surface of the test mass. This is verified by actuating on the main chain and the reaction chain separately and verifying that the beam spot correlates to the main chain.
Also, we centered the PR3 opleve in this past Friday. Sorry for not alogging.
