Figure 2

The ratio of three-pion Edgeworth radii in p-Pb over the linear fit in pp collisions, and the ratio of two-pion Edgeworth radii in Pb-Pb over the linear fit in p-Pb collisions versus $\langle{N_{\rm ch}}\rangle^{1/3}$ for low and high $\kT$ and $K_{\rm {T,3}}$ intervals. Errors are statistical, since systematic errors largely cancel in the ratio.
