Finding Problematic Calorimeter Regions Using Loose Electrons

Plots are of EM objects passing electron selection cuts:

  • pT > 25 GeV
  • EMfrac > 0.9
  • isolation < 0.15
  • HMx8 < 20
  • is_in_fiducial
  • id = 10,-11,11

    The boxes are colored according to calorimeter problem:

  • violet(6): tower 2 problem
  • blue(4): crate 9 problem (energy sharing)
  • green(8): signal cables were swapped
  • red(2): unknown

    There is a blank plot below with all boxes numbered.
