K$^{*0}$/K$^{-}$ and $\phi$/K$^{-}$ ratios as a function of $\langle\mathrm{d}N_{\mathrm{ch}}/\mathrm{d}\eta\rangle^{1/3}$ measured at mid-rapidity [44] in pp collisions at $\sqrt{s}$ = 2.76 TeV and 7 TeV [40], and Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}$ = 2.76 TeV. For Pb--Pb collisions, the $\phi$/K$^{-}$ values are exclusively from [18]; the previously published K$^{*0}$/K$^{-}$ measurements are compared to new measurements in finer centrality classes. Bars represent the statistical uncertainties, empty boxes represent the total systematic uncertainties, and shaded boxes represent the systematic uncertainties that are uncorrelated between centrality classes. The expectations from a thermal model calculation with chemical freeze-out temperature of 156 MeV for the most central collisions [45] are shown. The EPOS3 calculation of the K$^{*0}$/K and $\phi$/K ratios are also shown as a violet band for different centrality intervals [46]
