JimW, HugoP,

We started adjusting lockers on HAM3-ISI today. The iterative process starts with unlocking the ISI and adjusting the balancing. When we did so, Jim and I noticed the optics of MC2 and PR2 were swinging. We stopped while still having two of the four lockers (C and D) locked.

JeffB went in with AndresR and locked M2 and PR2. 

Jim and I went back in the afternoon. We adjusted the vertical position of the lockers. We ended up swapping the shims of locker D: initially 122, now 129.

We adjusted the zero of the vertical CPSs on the new locked position.

We plan on adjusting the lockers horizontally, and the horizontal CPSs tomorrow.
