0002 # While reducing the AOD data tier produced in 80X to miniAOD, the electron
0003 # MVAs are computed before slimming. However, the object updators in
0004 # egammaObjectModificationsInMiniAOD_cff are written for pat::Electrons.
0005 # Therefore, we must adapt the object modifiers to the AOD level such that the
0006 # MVA producer can run on electrons that are updated and correctly store the
0007 # conversion rejection variables.
0008 #
0009 # Little annoyance: updating the object also requires computing the HEEP value
0010 # maps for the gedGsfElectrons, even though they are recomputed later from the
0011 # reducedEgamma collections. Unfortunately we can't use these HEEP value maps
0012 # that already exists, because reducedEgamma in turn depends on the
0013 # electronMVAValueMap producer. Hence, this is a problem of circular
0014 # dependency.
