Figure 8

 (Left panel) The CME fraction extracted in Pb--Pb collisions at $\sqrt{s_\mathrm{{\rm NN}}} = 2.76$~TeV. (Right panel) The CME fraction extracted in Pb--Pb collisions at $\sqrt{s_\mathrm{{\rm NN}}} = 5.02$~TeV. The systematic uncertainty is shown as hatched band at zero line around the centrality value of 60\% The solid blue lines correspond to fit with a constant function to the data points.
