Subject: Aligning the OMC 

I replaced the 2'' AUX-AS combining BS with a freshly mounted 2'' HR mirror for 1064. The mirror is labelled 'Y1-2037-45-P', and had a comment on its case: 'V'. I aligned the AUX beam from the new HR mirror into the next iris, so AUX passes through irises both before and after the new optic. Now, AS does not go out to the AS PDs.

I mounted the old BS on the SP table in a random orientation.

I also dumped the beam transmitted through one of the AUX steering mirrors before the new HR mirror.
