BSC3 ACB rough position first look
I looked at the ITMx ACB position for any gross positional errors with respect to the ITMx. Athough the ISI and ITM are on stops the indication from the total station is the ACB will not interfere with the fine alignment of the ITMx. The ITMx rough position looking from the spool is good as far as the optic cap centering goes. I predict that we will need little elevation or lateral adjustment.
We won't know about longitudinal position or pitch and yaw until the ISI and SUS are leveled, TFs are done and the optic is suspended.
