Predictions from the hydrodynamical models for the centrality dependence for the SC($k,l,m$) [panels (a), (c), (e) and (f)] and NSC($k,l,m$) [panels (b) and (d)] in Pb--Pb collisions at $\sqrt{s_{_{\rm NN}}}=2.76$ TeV. The statistical uncertainties are shown with coloured bands. The predictions are compared with the ALICE results from Fig. \ref{s:Results_fig1} shown with red markers. The bands represent the statistical uncertainty of each model.
