The width (top) and effective ${\textpTm}$ (bottom) fit parameters as a function of the mean number of participants in pp, p\==Pb, and Pb\==Pb collisions at ${\FiveTeV}$ Vertical uncertainties are the standard error on the best-fit parameter values, while horizontal uncertainties reflect the uncertainty on $\langle N_{\mathrm{part}}\rangle$ from the Glauber calculations. Also shown are similar fit parameters from the same parameterisation of EPOS-LHC calculations as well as the relevant numbers extracted directly from those calculations.
