The vector of primary true trajectory IDs which contribute to the ND::THits which are constituents of this shower.

These are 'pseudo-primaries', which may or may not be primaries for a vertex.

If you want to be sure of finding a vertex, use the TP0DShower::Truth_TrajIDs list and get primary ID from the trajectories. See ND::TP0DReconModule::HitTruthPrimaryInfo for how they are calculated.
