Door covers are so tight the touch the ISI on both sides of HAM2.

IO closeout still to do::
- check beam on psl wall 
- flash IMC
- align REFL to HAM1 - needs coordination with ISC crew
- align HAM2 QPD
- check all baffles
- check POP/ALS path in HAM3
- align West side of HAM2 beams with viewport simulator.

Viewport simulater was crammed in the HAM2 clean room across the steps, so had to be moved, and will need to be wiped again before hanging on an open HAM2 door.
