Correcting arc 9 path length took longer than it should have because I got the sign for the GOF change wrong. This became clear only when the CC saw the result after the experienced operator steered arc 9 manually. It got much worse instead of better.

ABS=(hardware)-GOF-SOF.

Thus to move the beam out in 1 mm radius to gain Pi mm pathlength to take the dogleg off straight-ahead, GOF = -1.

Used XSEP8T and first shunt and then 8T09H to fix entry at 3C05.

While trying to bring these guys up to begin phasing, something with the DSETs seem to be preventing the script from running to completion. DSET values seemingly indefinitely bouncing between two values. We saw this same issue with cavities 1, 2, and 4. Cavity 3, however, tripped in the SlowGlos step of the script on both attempts to bring it up.

5th pass horizontal cavities are having issues when they hit the DSET ramp step of their turn on script (more detailed log entry to follow on this issue). I've contacted RF on-call in case this was a quick fix but they weren't sure what the issue was. Since they've been here all day and they shift plans says to only request remote assistance, I've decided to not call them in to fix the issue. Before, we give up completely on the horizontal separators, I wanted to give Software on-call a ring and rule out a software issue.
