| Top: LAr+MPD acceptance for $\nu_{\mu}$ \dword{cc} events as a function of muon transverse and longitudinal momentum. Bottom: Acceptance as a function of hadronic energy; the black line is for the full Fiducial Volume (FV) while the red line is for a $1 \times 1 \times 1$~m$^{3}$ volume in the center, where the acceptance is higher due to the better hadron containment. The blue curve shows the expected distribution of true hadronic energy in the \dword{dune} \dword{nd} flux normalized to unity; 56\% of events have hadronic energy below 1 GeV where the acceptance is high. |

| \dword{nd} samples in both \dword{fhc} (blue) and \dword{rhc} (red), shown in the reconstructed neutrino energy and reconstructed inelasticity binning used in the analysis, shown for a 7 year staged exposure, with an equal split between \dword{fhc} and \dword{rhc}. Backgrounds are also shown (dashed lines), which are dominated by \dword{nc} events, although there is some contribution from wrong-sign \numu background events in \dword{rhc}. |
