Keita, Corey, TVo
We finished aligning the OMC Trans path, it was quite difficult to lock the OMC, even with purge air turned down, but Keita was able to lock long enough for me to trace the beam to the viewport emulator. Keita will post a picture of the beam position in the emulator.
Yesterday we quoted a beam clearance for the fast shutter wire with the shutter closed, we've repeated the measurement with the shutter open and found that the clearance is grater than 12-13 mm, Keita wil post a picture of this as well.
We also took a ton of pictures of the table for future references, Corey will post pictures as a comment.
At the end of the day, we turned up the purge air and took the viewport emulator back down and placed it southwest of the PSL enclosure where Jason and I found it yesterday.
Photographic highlights from today's HAM6 work (names of photos describe the photos).

IMAG1026 (last): 2nd OMC REFL steering mirror.
The neat thing is that now both OM1's (L1 and H1) seem to want to be about 2 inches off in the -X ifo direction. So at least we're consistent? See LLO alog about OM1 here: LLO alog 37279 and compared to drawing D1000342.
