Figure 5

Elliptic flow coefficient $v_2$ as a function of $\pt$ for prompt $\Dzero$, $\Dplus$, and $\Dstar$ mesons for $\PbPb$ collisions at $\sqrtsNN=5.02~\TeV$ in the centrality class 10--30\%. The symbols are positioned horizontally at the average $\pt$ of the reconstructed D mesons. Vertical error bars represent the statistical uncertainty, empty boxes the systematic uncertainty associated with the D-meson anisotropy measurement and the event-plane resolution. Shaded boxes show the uncertainty due to the feed-down from beauty-hadron decays.
