Dielectron invariant-mass spectrum compared to the two different versions of the hadronic cocktail. In one version, shown with a dash-dotted magenta line, the charm contribution is obtained from PYTHIA via $\textit{N}_{\mathrm{coll}}$-scaling, while in the other version, shown with a dotted red line, a random correlation of dielectrons from charm decays is assumed. The statistical and systematic uncertainties of data are represented by vertical bars and boxes.
