H2 SUS ITMY Possible Rubbing
R. Lane, A. Ramirez

Possible rubbing point on both M0 and R0. 

Took a while to get the adjustment shown below because:
* Very little room to fit your hands in to make adjustments
* One cam on every OSEM position adjuster plate is almost touching (the pitch adjuster I think?) and so you cannot get the long socket we normally use for adjusting the Top Stage OSEM adjuster plate cams onto it.
* Not enough adjustment range to properly position the OSEM adjuster plate
* We are using cams, which limit your ability to adjust the plate in a controlled manner in any direction

Also, cannot visually check to see if the PUM OSEMs are rubbing or not:
Using a flashlight you can see through the little hole in the end of the OSEM and see the tip of the flag moving around. Cannot see the edge of the OSEM body to see if the flag is touching or not. They did not appear to be moving as if they were touching when I checked.
