The \pt-differential $v_2\{4\}$ for \pipm{}, \kapm{}, and p+\pbar{} measured in Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV compared with expectations of the same quantity from the CoLBT hydrodynamic model without quark coalescence  in 40--50\% centrality interval. The thickness of the curves reflect the uncertainties of the hydrodynamic calculations.
