ETMy Optical Lever Laser Swapped (WP 6013)
I swapped the oplev laser for the ETMy optical lever in order to address the problem noted by Sheila here. The laser will need 4-6 hours to come to thermal equillibrium.
The SN of the new laser is 130-1. This completes WP #6013.

Following up on this laser swap, the problem does not appear to be solved; see attached trend of ETMy oplev pitch & yaw. Will try power cycling the oplev AA chassis during the next Tuesday maintenance window.
