# Figure 8

 Top panels: average of $\Dzero$ and $\Dplus$ $v_2$ as a function of $\pt$ for $\PbPb$ collisions at $\sqrtsNN=5.02~\TeV$ in the small-$\qTPC$, large-$\qTPC$ (see text for details) and unbiased samples, in the 10--30\% (left) and 30--50\% (right) centrality classes. Bottom panels: ratios of the measured $v_2$ in the ESE-selected classes to the one obtained from the unbiased sample.
