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.
