Subject: installing the new dirchoic mirros in PR3/SR3 

When installing the dichroics we need to pay attention to the wedge angle.  I didn't, so the ghost beam is currently point up and to the right (when facing the optic).  We should think carefully about where we want the ghost beams to go.

I also was using TT SN003, which I believe was being used for PR2.  However, I don't think we want to install dichroics in the PR2, and we might want to put all the tip-tilts back in the same spots they were in before.  We therefore may want to put the old optic back in SN003, and put the dichroics in SN005 (PR3) and SN001 (SR3) (see 7601).
