31   We use PF-based isolation with a cone size of $\Delta R<0.3$, using the effective area rho corrections documented at~\cite{ref:Egammaiso},
32   and we require a relative isolation $<$ 0.15.
33   Electrons in the transition region defined by $1.4442 < |\eta_{SC}| < 1.566$ are rejected.
34 < Electrons with a selected muon with \pt $>$ 10 GeV within $\DeltaR<0.1$ are rejected.
34 > Electrons with a selected muon with \pt $>$ 10 GeV within $\Delta R<0.1$ are rejected.
35   The electron selection requirements are listed in Table~\ref{table:electrons} for completeness.

86 \subsubsection{PF Leptons}

88 For consistency with pfmet, both electrons and muons are required to be reconstructed as PF electrons and PF muons, respectively,
89 with \pt $>$ 20 GeV. For defining the dilepton invariant mass, the 4-momenta of the PF leptons are used.
