 | Fitted $m_D$ distribution. Both plots show the same data sample with (left) linear and (right) logarithmic vertical scales. The curves show the results of the first fit, described in Sec.~\ref{sec:fit:mass}: the total (solid black), the background component (dotted), and the signal component (grey, right only). |

 | Decay time projection from the fit for separation of prompt and secondary candidates. The curves show the results of the fit described in Sec.~\ref{sec:fit:time:lifetime}: the total (solid black), the prompt component (solid green), the secondary component (dot-dashed blue), and the combinatorial component (dashed red). Both plots show the same data sample with linear (top) and logarithmic (bottom) vertical scales. |

 | Fitted $(m_D, \Delta m)$ distributions. The upper row shows the $m_D$ projection and the lower row $\Delta m$. The left column shows \Dstarp candidates and the right column \Dstarm. The signal and background components are shown separately (signal as solid grey, \Dz background dashed, combinatoric background dotted, and the sum as solid black). |
