This page documents BES-II run-dependent QA

Algorithm packages:
 
Analysis cuts:
  • Event level cuts:
    • |vz| < 145 cm
    • vr < 2 cm
  • Pileup rejection:
    • Pileup rejection based on RefMult vs. bTofMatch will only be determined AFTER bad run rejection
    • Applied in StRefMultCorr
  • Track quality cuts:
    • Primary tracks
    • |eta| < 1.5
    • NHitsFit >= 10
    • DCA < 3 cm
    • 0.06 < pT < 2 GeV/c
