Finished backing out and touching up steering up to 8R. Currently the only IDX showing response is IIX6S01 which is a combination of 4S and 6S steering.

The position at 4S01 and 6S01 is very hard to minimize without blowing up the linac orbit so we decided on a middle ground. This shows as coming in with a high launch into 4S and and wave in the 6L.

Orbit found after pulling the 5R dumplette (Fig. 1). MXU6R04 is about 3% off so tried to see if I can find a better solution.

Was able to get it slightly closer to design. Was able to get everything nice and flat except the launch into the linac... IIX1L02 not reading anything so seems to be find here...

Zerod correctors and did another round of shunt steering. Brought them closer to design but there is a wave in 6L that cannot be removed without negative effect on 6S01 vertical position and causing IIX6S01 to scream.

Cleaned up the 6L orbit but still coming in high on 6S01 causing the IIX6S01 to scream.
