Comparison of the azimuthal-correlation distributions of D mesons with charged particles obtained for $\Dzero$, $\Dplus$ and $\Dstar$ mesons Comparison of the azimuthal-correlation distributions of D mesons with charged particles obtained for $\Dzero$, $\Dplus$ and $\Dstar$ mesons for $5< p_{\rm T}^{\rm D}< 8~\gevc$, $p_{\rm T}^{\rm assoc} > 1 ~\gevc$ in pp collisions at $\sqrts=7~\tev$ (left panel) and for $8< p_{\rm T}^{\rm D}< 16~\gevc$, $p_{\rm T}^{\rm assoc} > 1 ~\gevc$ in $p-P$ collisions at $\sqrtsNN=5.02~\tev$ (right panel). The statistical uncertainties are shown as error bars, the $\Delta\varphi$-uncorrelated systematic uncertainties as boxes, while the part of systematic uncertainty correlated in $\Delta\varphi$ is reported as text (scale uncertainty). The latter is largely uncorrelated among the D-meson species.
