Invariant-mass distributions of \Dzero-, \Dplus-, and \Lc-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.
