Figure 2

Centrality dependence of $\rho \left(v_{\rm 2}^{2}, v_{\rm 3}^{2}, [ p_{\rm T} ] \right)$ in Pb--Pb collisions, shown by the solid circles. The statistical (systematic) uncertainties are shown as vertical bars (boxes). The initial-state estimations (ISE) as well as IP-Glasma+MUSIC+UrQMD~ and v-USPhydro~ hydrodynamic model calculations are compared with data.
