Neutrals

• Given a DNeutralParticleHypothesis or DNeutralShower object, how do I get the FCAL/BCAL shower objects?

//given a hypothesis, get the neutral shower:
const DNeutralShower* locNeutralShower = NULL;
locNeutralParticleHypothesis->GetSingle(locNeutralShower);
 
//given a neutral shower, get the BCAL shower:
const DFCALShower* locFCALShower = NULL;
if(locNeutralShower->dDetectorSystem == SYS_FCAL)
   locNeutralShower->GetSingle(locFCALShower);
 
//given a neutral shower, get the FCAL shower:
const DBCALShower* locBCALShower = NULL;
if(locNeutralShower->dDetectorSystem == SYS_BCAL)
   locNeutralShower->GetSingle(locBCALShower);
