Absent the BPMs at 4E01, 4E03, 4A01, and with the positions at 4A02 and 4A03 suspiciously immobile, I had to perform this optimization on the viewers. With all 4EH correctors set to -700 G-cm and all relevant 4S and A correctors apart from MBC4S10H zeroed, which was used to set 4E02.XPOS at 5.5, I iterated between the 4E02 and 4A01 viewers to set the dogleg shunt. IDXs in the region are quiet.

Optimized 4S steering as best I could considering the strange vertical angle at the end of 4L. The orbit was similar last run; IPM4S01.YPOS seems to inevitably be high and cannot be brought down without severely screwing up 4L. I did some work in 3R, including a little shunt steering which seemed to take out some of the ring in 4L. The shunts in the second step of 4S (4S05 and 4S06) are set asymmetrically to get orbit level at the exit of the step. Vertical corrector content was reduced to zero in the relevant parts of 3R and 4S.
