Subject: New EOM mount in place 

EOM is remounted on the fancy-pants new mount that I crafted.  EOM is also aligned.  2 green mirrors (the first ones to see the beams coming onto the PSL table from the arm transmissions) had to be moved so I could fit the mount in, since the new mount is bigger than the old one.  I put them back, and approximately realigned them, but didn't do any fine alignment.  This must be done before looking at beatnotes again.

After playing with the EOM, the MC was flashing on higher order modes.  The PSL beam has been realigned to make the MC lock on TEM00, and Suresh helped me center on the WFS and MC2T.

Things look okay for now.  Next step:  Kiwamu needs to find his happy mode cleaner place, and we'll realign the PSL beam to the MC.  The PSL-MC axes were mismatched pretty badly according to Suresh anyway, so this had to be done no matter what.
