Figure 3: Mean transverse momenta for K*$^{0}$ and $\phi$ are compared with those for K$^{0}_{\mathrm{S}}$, $\Lambda+\overline{\Lambda}$, $\Xi^{-}+\overline{\Xi}^{+}$, and $\Omega^{-}+\overline{\Omega}^{+}$ in pp collisions at $\sqrt{s}$ = 13 TeV as a function of $\langle \mathrm{d}N_{\mathrm{ch}}/\mathrm{d}\eta\rangle_{|\eta|<0.5}$ [arXiv:1908.01861]. The values for $\Xi^{-}+\overline{\Xi}^{+}$ are shifted horizontally for visibility. Bars represent  statistical uncertainties, open boxes represent total systematic uncertainties, and shaded boxes show the systematic uncertainties that are uncorrelated between multiplicity classes.
