(Top) The dependence of $\Delta \gamma_{1,1}$ on $v_2$ for shape selected events together with a linear fit (dashed lines) for various centrality classes. (Bottom) The centrality dependence of the CME fraction, $f_{\mathrm{CME}}$, extracted from the slope parameter of fits to data and MC-Glauber, MC-KLN CGC, and EKRT models, respectively. The dashed lines indicate the physical parameter space of the CME fraction, while the points are slightly shifted along the horizontal axis for better visibility. Figures from Ref. .
