PreSelect Cuts

  • For a given DChargedTrack, at least one hypothesis must have a hit in either: BCAL/FCAL/TOF/SC.
  • For a given DNeutralShower, it must at least have a shower energy of 100 MeV/c.
  • For neutral showers in the BCAL, they must have hits in at least 2 cells.

Kinematic Fit

  • If a kinematic fit has been performed, it must have converged.
