$v_2$, $v_3$, and $v_4$ measured for unidentified charged particles as a function of transverse momentum for various centrality classes. The dashed line represents the WHDG model calculations for neutral pions $v_2$ extrapolated to the LHC collision energy. For clarity, the markers for $v_3$ and $v_{4/\Psi_{2}}$ results are slightly shifted along the horizontal axis. Error bars (shaded boxes) represent the statistical (systematic) uncertainties.
