  • Normalized chi square smaller than 5.
  • Upper threshold of 1 GeV on energy deposit in ECAL (in a 9cm radius cylinder), to ensure that particles do not shower until they enter the HCAL.
  • Upper threshold of 8 GeV on energy deposit in ECAL between to concentric cylinders (respective radii: 15 and 35 cm) arround impact point, to ensure isolation against neutral particles.
  • Lower threshold of 50 GeV on energy deposit in 3x3 Hadronic Calorimeter tower cluster.
