Comparison of near-side associated peak yields (top row) and widths (bottom row) as a function of the D-meson $\pt$, for \pPb collisions in three different centrality classes, 0--20\% (blue circles), 20--60\% (red squares), and 60--100\% (green diamonds). The results are presented as a function of the D-meson $\pt$, for $\ptass > 0.3$ \GeVc, $0.3 1$ \GeVc (from left to right). Statistical and systematic uncertainties are shown as vertical error bars and boxes, respectively. The points and error boxes for 0--20\% (60--100\%) collisions are shifted by $\Delta\pt = -0.2$ ($+0.2$) \GeVc
