Check Electron Analyzer in 2015MiniAOD branch

[katilp]

Following the general recommendations in #64 check the Electron Analyzer

• in particular, check the input for electronID with respect to https://twiki.cern.ch/twiki/bin/view/CMSPublic/WorkBookMiniAOD2015#Electrons:

  The set of embedded electron IDs has been updated to contain: cut-based Spring15_25ns_V1 Spring15_50ns_V1 (and PHYS14_PU20bx25_V2), heepElectronID_HEEPV60, mvaElectronID_Spring15_25ns_nonTrig_V1

  • The current code uses PHYS14_PU20bx25_V2 but Spring15_25ns_V1 looks more recent.
  • Some documentation for 2016-2018 MiniAOD is available in https://twiki.cern.ch/twiki/bin/viewauth/CMS/EgammaMiniAODV2#Accessing_ID_result (for general guidance only as it is not necessarily valid for this early MiniAOD version for 2015)
  • General Run2 Electron ID documentation has a link to older values under https://twiki.cern.ch/twiki/bin/view/CMS/CutBasedElectronIdentificationRun2#Archive_of_previously_recommende
  • THIS LINK looks like being the correct reference information https://twiki.cern.ch/twiki/bin/view/CMS/CutBasedElectronIdentificationRun2Archive#Recipe_for_regular_users_for_7_4

• Check also what is returned by el.ecalPFClusterIso() and if the description of the returned values in https://github.com/cms-sw/cmssw/blob/CMSSW_7_6_X/DataFormats/PatCandidates/interface/Electron.h#L121-L131 still holds
