Functions
std::pair< float, float >	xAOD::PVHelpers::getZCommonAndError (const xAOD::EventInfo *eventInfo, const xAOD::EgammaContainer *egammas, float convPtCut=2e3)
	Return zCommon and zCommonError.
float	xAOD::PVHelpers::getVertexSumPt (const xAOD::Vertex *vertex, int power=1, bool useAux=true)
	Loop over track particles associated with vertex and return scalar sum of pT^power in GeV (from auxdata if available and useAux = true).
TLorentzVector	xAOD::PVHelpers::getVertexMomentum (const xAOD::Vertex *vertex, bool useAux=true, const std::string &derivationPrefix="")
	Return vector sum of tracks associated with vertex (from auxdata if available and useAux = true).
const xAOD::Vertex *	xAOD::PVHelpers::getHardestVertex (const xAOD::VertexContainer *vertices)
	Return vertex with highest sum pT^2.
TLorentzVector	xAOD::PVHelpers::getTrackAtFirstMeasurement (const xAOD::TrackParticle *tp)
	Return track at first measurment, useful as proxy to conversion vertex pT.
bool	xAOD::PVHelpers::passConvSelection (const xAOD::Photon *photon, float convPtCut=2e3)
	Check if photon is converted, and tracks have Si hits and pass selection.
bool	xAOD::PVHelpers::passConvSelection (const xAOD::Vertex &conversionVertex, size_t i, float convPtCut)
	Check if track i of conversion vertex pass selection (Si hits and pt).
