Charged particle $v_2\{2\}$ and $v_3\{2\}$ as a function of centrality in \OO (left) and \NeNe (right) collisions. The data points are the same as those in Fig. \ref{fig:vnNeNeOO}. The measurements are compared with IP-Glasma+JIMWLK+MUSIC+UrQMD and 3DGlauber+MUSIC+UrQMD calculations with PGCM input, as well as AMPT with NLEFT input.
