◆ Accessor

using TrackTraits< xAOD::TruthParticle >::Accessor = SG::ConstAccessor<float>

are these TrackParticle specific variables really needed ?

? Surely if we need them then we should only be calling them in some special object that explicitly wants TrackParticles

what are we going to do with photons ?

For a track based analysis the charge should never by 0 but if we are using signed pt / p etc this will likely cause issues down the line especially if we start to throw exceptions for divide by 0 errors
