Transcript and Presenter's Notes

Title: PRIMEX database, tables introduced:


1
PRIMEX database, tables introduced
  • LMSref filter_pos default value 0 (
    unknown)
  • Values from Sam are loaded (1, 2 or 3)
  • crystal, glass pi0_gain runs 4829-5059 and
    5115-5330 are covered by two tables from carbon
    production runs
  • crystal, glass mc_gain gains to be used for MC
  • crystal, glass gk_mc_gain gain corrections to be
    used
  • with gk MC, pi0 calibration was simulated with
    pi0 angular/energy spectrum close to observed
    one.
  • PRIMEX database, tables updated
  • hycal_timing offset, sigma
  • PRIMEX database, tables to be introduced
  • Timing offset and a,b coef. for en. Resolution
    adc status
  • For channels which were not working well

2
Recn. program issues
  • Hycal algorithm, can we switch to old one
  • (in principle)
  • Fastbus errors are counted and event is not
    rejected.
  • Nhit max and min elements in cluster cuts are
    changed?
  • Island algorithm could be introduced (we have
    clusters profiles)
  • Coordinate correction is known from the MC
  • Depth correction has to be increased by 1.1 as
    follows from detailed MC studies and data
    confirms with statement

3
Skim files
  • Pi0 pass 2a
  • Compton for double compton runs and for
    production runs
