Figure 5

Centrality dependence of the $p_{1}$ parameter from a linear fit to the difference between opposite and same charge pair correlations for $\gc$ and from linear fits to the CME signal expectations from MC-Glauber , MC-KLN CGC  and EKRT  models (see text for details). Points from MC simulations are slightly shifted along the horizontal axis for better visibility. Only statistical uncertainties are shown.
