"Table 4" of "Measurement of dielectron production in central Pb-Pb collisions at $\sqrt{{\textit{s}}_{\mathrm{NN}}}$ = 2.76 TeV"

Data-to-cocktail ratio as a function of the invariant-mass. In the hadronic cocktail, random correlations of dielectrons from charm decays are assumed to simulate the effects of the interaction between charm quarks and the medium. The statistical and systematic uncertainties of data are represented by vertical bars and boxes.
