Supplementary figures: “Centrality evolution of the charged–particle pseudorapidity density over a broad pseudorapidity range in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV"

This public note provide supplementary figures for the Letter on "Centrality evolution of the charged–particle pseudorapidity density over a broad pseudorapidity range in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV" (arXiv:1509.07299). The figures are the ratio of central to peripheral charged–particle pseudorapidity density, as well as the distributions with the various fitted functions mentioned in the Letter.
