Functions
TVectorD	FCCAnalyses::SmearObjects::TrackParamFromMC_DelphesConv (edm4hep::MCParticleData aMCParticle)
	for a given MC particle, returns a "track state", i.e.
ROOT::VecOps::RVec< edm4hep::TrackState >	FCCAnalyses::SmearObjects::mcTrackParameters (const ROOT::VecOps::RVec< edm4hep::ReconstructedParticleData > &allRecoParticles, const ROOT::VecOps::RVec< edm4hep::TrackState > &alltracks, const ROOT::VecOps::RVec< int > &RP2MC_indices, const ROOT::VecOps::RVec< edm4hep::MCParticleData > &mcParticles)
	used to validate the method above.
TVectorD	FCCAnalyses::SmearObjects::CovSmear (TVectorD x, TMatrixDSym C, TRandom *ran, bool debug)
	generates random values for a vector, given the covariance matrix of its components, using a Choleski decomposition.
