Detailed Description

Vary energy of PFCandidates which are (are not) within jets of Pt > 10 GeV by jet energy uncertainty (by 10% "unclustered" energy uncertainty)

NOTE: Auxiliary class specific to estimating systematic uncertainty on PFMET reconstructed by no-PU MET reconstruction algorithm (implemented in JetMETCorrections/Type1MET/src/PFNoPUMETProducer.cc)

In case all PFCandidates not within jets of Pt > 30 GeV would be varied by the 10% "unclustered" energy uncertainty, the systematic uncertainty on the reconstructed no-PU MET would be overestimated significantly !!
