(Left) The centrality dependence of $\Delta \delta_1$ measured in Pb--Pb collisions at $\sqrt{s_\mathrm{{\rm NN}}} = 5.02$ TeV. The curve (denoted as BW-LCC) presents the blast-wave parametrization coupled to local charge conservation effects The model is tuned to reproduce the measured values of $\Delta \delta_1$ (see text for details). (Right) The comparison of the centrality dependence of the CME-sensitive correlator $\Delta \gamma_{1,1}$ with expectations from the BW-LCC model.
