Continued from yesterday running

Good - Run 7734 - First production run with new/bad moller Quads tune. Looks good - Cut 12 X BPM out > 0.5 mm, < -1.5 mm
Good - Run 7735 - Production run with new/bad moller Quads tune. Looks good - Cut 12 X BPM out > 0.5 mm, < -1.5 mm
Good - Run 7736 - Production run with new/bad moller Quads tune. Looks good - Cut 12 X BPM out > 0.5 mm, < -1.5 mm
- Lots of RHRS asymmetry noise.
- Cut out from 175k onwards to avoid any potential problems with the RQ1 communication failure
Good - Run 7737 - Production run with new/bad moller Quads tune. Looks good
- Cut 12 X BPM out > 0.5 mm, < -1.5 mm.
- Lots of RHRS asymmetry noise.

Good - Run 7738 - Production run with new/bad moller Quads tune. Looks good - Cut 12 X BPM out > 0.5 mm, < -1.5 mm
- Lots of RHRS asymmetry noise.
- Tried a brief period of FFB On, which caused quite a bit of noise.
- Generally OK though
Good - Run 7739 - Production run with new/bad moller Quads tune. Looks good - Cut 12 X BPM out > 0.5 mm, < -1.5 mm
- Lots of RHRS asymmetry noise.
Good - Run 7740 - looks good. Cut 12 X BPM out > 0.5 mm, < -1.5 mm
Good - Run 7741 - looks good. Cut 12 X BPM out > 0.5 mm, < -1.5 mm
Good - Run 7742 - big jump in bpm 12X yield at the beginning of the run, but honestly it is probably fine to leave it in there.
Good - Run 7743 - Very short run. Looks good though

Continued in tomorrow's run here

Running with FFB off
Moller quads failed and we got a different tune over night. The data seems OK anyway
Run 7761 for Compton tuning on C-1%, needed vertical table move

BMOD tune seems OK.
I found another bug in code - was always using 4aX BPM even in 1X case for corrections... now fixed
It appears 1X 15746 BMOD analysis is the best for the last few days of running. Needs re-analysis to pick up pedestal fix and get the full run lists all analyzed again.
