Production Run List - Slug 203 - IHWP IN - Flip-RIGHT - Production

  • Good - Run 7993
  • NeedCut - Run 7994 -- even after cutting out 110k-115k entries, the shift in bpm12X is still larger than 1mm, need further offline analysis
  • Good - Run 7996
  • Good - Run 7998
  • Good - Run 7999
  • Good - Run 8000
  • Good - Run 8012 -- obvious energy shift, resulting in drop of yield in both arms
  • NeedCut - Run 8013 -- trippy in the last 100k entries (minirun 5), resulting in larger width, cut out some large excursions to bring down the reg_asym_us_avg rms
  • NeedCut - Run 8014 -- large bpm12X excursion (minirun 2: large reg_asym_us_avg.rms ~950 ppm)
  • Good - Run 8015

Production Run List - Slug 204 - IHWP OUT - Flip-RIGHT - Production

  • Junk - run 7995 -- C-hole
  • Junk - Run 7997 -- C-hole
