TrackTraits< xAOD::TauJet > Struct Reference

This is coming from the TauJet, which is not so clean a class - the "tau" candidate does not even have a z0, or d0 value - any combination of tracks that has a 4-vector, can have a z0 and a d0 value, the TauJet class is somewhat messy and difficult to actually use like an actual "particle", so we aren't really going to bother.
