Correlations $C_\mathrm{p,K}$ (left), $C_\mathrm{Q,p}$ (middle), and $C_\mathrm{Q,K}$ (right) are shown as a function of centrality in Pb--Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02$ TeV. Colored lines represent Thermal-FIST (TheFIST)  model calculations for the canonical ensemble (CE) with different correlation volumes ($V_{c}$). The statistical (systematic) uncertainties are represented by vertical bars (boxes).
