 Average of the azimuthal-correlation functions of $\Dzero$, $\Dplus$, and $\Dstar$ mesons with associated particles, after the subtraction of the baseline, for \pPb collisions in three different centrality classes, 0--20\% (blue circles), 20--60\% (red squares), and 60--100\% (green diamonds). The functions are shown for $3 < \ptD < 5$~\GeVc, $5~< ~\ptD~< ~8$~\GeVc, and $8 < \ptD < 16$~\GeVc (from left to right) and $\ptass > 0.3$~\GeVc, $0.3 < \ptass < 1$~\GeVc, and $\ptass > 1$~\GeVc (from top to bottom). Statistical and $\Dphi$-dependent systematic uncertainties are shown as vertical error bars and boxes, respectively, while $\Dphi$-independent uncertainties are written as text. The uncertainties from the subtraction of the baseline are displayed as boxes at $\Dphi > \pi$.
