Transverse momentum distributions $\dNdydpt$ of prompt $\Dzero$ mesons from the analysis with (open marker) and without (full marker) decay-vertex reconstruction in the 0--10\% and 30--50\% centrality classes in \PbPb collisions at $\sqrtsNN = 5.02 \TeV$. Statistical uncertainties (bars) and systematic uncertainties (boxes) are shown.
