Centrality dependence of $(2\kappa^{11}_\mathrm{Q,K}-\kappa^{11}_\mathrm{p,K})/\kappa^{2}_\mathrm{K}$ (left) and $(2\kappa^{11}_\mathrm{Q,p}-\kappa^{11}_\mathrm{p,K})/\kappa^{2}_\mathrm{K}$ (right) in Pb--Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02$ TeV. Thermal-FIST (TheFIST)  model calculation for canonical ensemble (CE) with a correlation volume of $V_\mathrm{c}=2.6\mathrm{d}V/\mathrm{d}y$ is represented by the colored band. The statistical (systematic) uncertainties are represented by vertical bars (boxes).
