Invariant-mass distributions of $\Dzero$-, $\Dplus$-, and $\Lambda^{+}_{\rm c}$-hadron candidates, and their charge conjugates in selected $\pt$ intervals. The blue solid lines show the total fit functions as described in the text and the red dashed lines show the fit function describing the combinatorial background. For $\Dzero$-meson candidates, the solid green line represents the contribution of the reflections. The mean ($\mu$) and fixed standard deviation ($\sigma$) of the signal fit function, along with the raw-yield ($S$) values, are reported together with their statistical uncertainties resulting from the fit. The fraction of non-prompt candidates in the measured raw yield ($f_{\text{non-prompt}}^{\mathrm{raw}}$) is reported with its statistical and systematic uncertainties.
