Centrality dependence of $\rho \left(v_{\rm 2}^{2}, [ p_{\rm T} ] \right)$ in Pb--Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV . The statistical (systematic) uncertainties are shown with vertical bars (filled boxes). The initial state estimations are represented by lines in the figures, while IP+Glasma+MUSIC+UrQMD , v-USPhydro , Trajectum , and JETSCAPE  hydrodynamic model calculations are shown with hatched bands.
