Detailed Description

template<typename T, typename Textractor>
class PFJetMETcorrInputProducerT< T, Textractor >

Produce Type 1 + 2 MET corrections corresponding to differences between raw PFJets and PFJets with jet energy corrections (JECs) applied

NOTE: class is templated to that it works with reco::PFJets as well as with pat::Jets of PF-type as input
