- Good - Run 7808 - Looks good. Cut out > 0.0 and < -1.5 mm BPM 12X
- Good - Run 7809 - looks good. Coming back from a downtime
- Good - Run 7810 - Looks good. Add BPM 12X cut out > 0.5 mm, < -1.0

Non-Production Runs and Bad Runs
Issues
- Running with FFB off
- Removed BPM Y burp cuts (again, retroactively)
- BPM 12X (and all monitors) see regular short spikes (still) - it seems to be getting worse
- BPM Noise issues
- BPM 12X jumps are hard to cut - Robert is working on a 12X burp cut estimate for that
- BPM Y has noise when burp cut is off, but it doesn't seem to negatively impact asymmetry or detector yields, and is smaller than target size
- BPM Y burp cut ON kills BMOD coil 6
Updates
- BMOD tune seems OK.
