Late Entry: steering to address ILM7S01 trips

Honestly all of this may have been placebo and we just needed to wait out whatever was shaking, but I mostly touched the 3rd, 4th, and 5th pass vertical west recombiner. Some of it seemed to help just based on being able to send beam.

Extreme vertical jiggle on 2A

21 hours 30 minutes ago
Log Number: 4531492Logbook(s): Entry Makers: deirBody: 

Almost looks like BBU...

Figures 3-5. The SLM pictures are only with D beam in the machine. We don't really see this with xC in the mix.

Figures 1 and 2 are from the 3C12 waveforms. We turned off FFB to see if it was correcting for whatever was going on, and lo and behold, this popped out. That trip data captured pretty large vertical oscillations in the 3C12 line.

The 7S01 trips have been a pain tonight.
