Detailed Description

The DetEff class.

This class stores a set of yield trees needed to calculate detection efficiencies

DetEff tree used to store full kinematics of

• total signal events (users should fill trueMC)
• accepted signal events (users should fill reconstructed)
• Store accepted background events (users should fill reconstructed)
• Basic stats

USE:

Once per event:

  if(event.Reconstructed().ID.isSet(ant::TID::Flags_t::MC))
          detection_efficiency.SetEventType(signal,decay);

If signal event, and MC event, loop over tagger channels:

  for (const auto &tc : event.Reconstructed().TaggerHits){
     promptrandom.SetTaggerHit(tc.Time);
     detection_efficiency.TrackSignalEvent(*pi0, 0, tc, promptrandom);
  }

After all cuts, if MC event, loop over tagger channels:

  for (const auto &tc : event.Reconstructed().TaggerHits){
     promptrandom.SetTaggerHit(tc.Time);
     detection_efficiency.AcceptEvent(Meson,Meson_time, tc,promptrandom);
  }
