Figure Caption

Left panel: raw $p_{\rm T,ee}$-differential yield ($S$) in peripheral (70--90\%) Pb--Pb collisions at \fivenn for $0.7 \leq \mee < 1.1$~\GeVmass overlaid with the opposite charge-sign distribution ($OS$) and the same charge-sign spectrum multiplied by the acceptance correction factor $R_{\rm acc}$ ($B$). Right panel: signal over background as a function of \ptee in peripheral (70--90\%) Pb--Pb collisions at \fivenn for $0.7 \leq \mee < 1.1$~\GeVmass.
