Centrality evolution of the difference between opposite- and same-charge pair correlations for $\delta_{\alpha \beta}$ (top panel) and $\gamma_{\alpha \beta}$ (bottom panel) compared to model calculations: blast wave (BW) parameterisation  coupled to local charge conservation (LCC) effects (blue curves) and Anomalous Viscous Fluid Dynamics (AVFD)  (green curves). The BW+LCC model is tuned to reproduce the centrality dependence of $\Delta\delta_{\alpha\beta}$, while AVFD is tuned to describe simultaneously the centrality dependence of $\Delta\delta_{\alpha\beta}$ and $\Delta\gamma_{\alpha\beta}$. Bars (boxes) denote statistical (systematic) uncertainties on the data points, while the thickness of the curves represents the uncertainties on the model calculations.
