Production Run List - Slug 70

• Run 4585
  • BCM double peaking on double difference
• Run 4586
  • Large difference between BPM4A-X and its complement
• Run 4587
• Run 4588
• Run 4589
  • BCM double differences is still weirdly peaked, not terribly so
• Run 4590
• Run 4591
• Run 4592
• Run 4593
• Run 4594
• Run 4595

Production Run List - Slug 71

So this slug had a lot of problems with widths due in part to a unchecked raster size and unsuitable optics.

CONFIG CHANGE: FFB On, Aq ON, BMW On, FF On

• Run 4596
  • Small BPM drifts on 4aX, advise doing nothing

CONFIG CHANGE: FFB Off, Aq On, BMW On, FF On

• Run 4621
  • Main Detectors
    • Widths finally down again
  • BCMs
    • BCM wings again
• Run 4622
• BCMs
  • Wings

CONFIG CHANGE: FFB Off, Aq On, BMW On

• Run 4623
• Run 4624
• Run 4625

The following runs had bad widths due to the raster and optics being bad

• Run 4606
  • Main Dets
    • Widths untenable
  • BPMs
    • BPM drifts at start of run, but in all honesty, does it matter?
