Detailed Description

Vary energy of PFCandidates coinciding in eta-phi with selected electrons/muons/tau-jets/jets by electron/muon/tau-jet/jet energy uncertainty.

NOTE: Auxiliary class specific to estimating systematic uncertainty on PFMET reconstructed by MVA-based algorithm (implemented in RecoMET/METPUSubtraction/src/PFMETProducerMVA.cc)
