Ok, I think this is quite confusing. I see that you replaced the useRhoActiveAreaCorrections and useDeltaBetaCorrections flags in PatUtilities.cc for the electrons in getRelativeIsolation function, so the first one has priority. I think we should have separate isolation flags for electrons or muons, or simply hardcode them ( @kreczko might have a better idea). Also, delta beta corrections flag is set to false in the electron unfolding selection, which means that loose muon veto is applied without delta beta corrections. In the [analysis tools](https://github.com/BristolTopGroup/AnalysisSoftware/blob/master/src/Selections/TopPairEPlusJetsReferenceSelection.cpp#L193), we're using the [default value](https://github.com/BristolTopGroup/AnalysisSoftware/blob/master/interface/RecoObjects/Lepton.h#L58) which is true (DB corrections applied). Again, relates to @jjacob's synchronisation work.
