Two- and three-pion Exponential fit parameters versus $\langle{N_{\rm ch}}\rangle$ in pp, p-Pb and Pb-Pb collision systems for low and high $\kT$ and $K_{\rm{T,3}}$ intervals. Top panels show the Exponential radii $R^{\rm Exp}_{\rm inv}$ and $R^{\rm Exp}_{\rm inv,3}$ scaled down by $\sqrt{\pi}$ and bottom panels show the effective intercept parameters $\lambda^{\rm Exp}_{\rm e}$ and $\lambda^{\rm Exp}_{\rm e,3}$. Same details as for Fig.3.
