ITMY and ETMX OpLevs re-aligned
We found that the optical lever for ETMX was starting come off the QPD's linear regime (41 urad in pitch) and so it seemed like a good time to re-align.

ITMY's optical lever has been completely off of the QPD for a little while now but we were able to recover the beam without opening the covers.

The last time a fine alignment was done was January 8th, 2014.
