Figure Caption
Comparison of D-meson - charged particle azimuthal correlation distributions in p-Pb collisions at sqrt(sNN) = 5.02 TeV in three different ZNA centrality ranges (0-20%, 20-60%, 60-100%), after subtraction of the baseline, for 9 different ranges of pT(D) and of pT(assoc).
Average of D0, D+, D*+ correlation distributions, with D mesons in -0.96 < y^D_cms < 0.04 and charged particles in |eta|<0.8.
Correlations are shown for |∆η| < 1 only.
Statistical uncertainties are shown as error bars, uncorrelated systematic uncertainties as error boxes, correlated systematic uncertainties are written as a label. The uncertainty from the evaluation of the baseline is plotted as a closed box at dPhi > pi.
Only primary pions, kaons, protons, electrons and muons are correlated to D-mesons.

Standard D2H cuts for the D-meson selection, with centralty-optimization for the D0 meson. Standard D-h analysis cuts for associated particles
Correlations are shown for |∆η| < 1 only.
Statistical uncertainties are shown as error bars, uncorrelated systematic uncertainties as error boxes, correlated systematic uncertainties are written as a label. The uncertainty from theevaluation of the baseline is plotted as a closed box at dPhi > pi.
