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