# Figure 9

 For each set of events characterised by $\alpha_{\rm{ZN}}^{\rm{cut}}$, the measured values of coefficient $c_{\rm 1}$ as a function of estimated values of mean rapidity-shift obtained using TGMC as described in the text. The results are shown for different centralities. The uncertainties for \textit{$\langle y_0 \rangle$} shown are statistical and within its symbol size. The lines are linear fits passing through the origin.
