Centrality dependence of $\kappa^{11}_\mathrm{Q,p}/\kappa^{2}_\mathrm{Q}$ (left) and $\kappa^{11}_\mathrm{Q,K}/\kappa^{2}_\mathrm{Q}$ (right) in Pb--Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02$ TeV. Colored lines represent Thermal-FIST (TheFIST)  model calculations for canonical ensemble (CE) with different correlation volumes ($V_{c}$). The statistical (systematic) uncertainties are represented by vertical bars (boxes).
