As the higher $D^0 \rightarrow K\ell\nu$ branching fraction than $D^0 \rightarrow \pi\ell\nu$ could out-weigh the ($\ell \rightarrow \pi$) / ($\ell \rightarrow K$) mis-id rates.
Decay files tested and HighVisMass cut working. Using the "Child Selector" method for clarity due to duplicate "K-" in the decfiles, alternative was GNINTREE.

## Note on Issue found in Analogue DecFiles
These models use the Lb2Baryonlnu model and work from the analogues made for the D0->Kpi mode in [!1144
](https://gitlab.cern.ch/lhcb-datapkg/Gen/DecFiles/-/merge_requests/1144). In investigating this model however we noticed that there is a mistake with the $\bar{\Lambda_c^{*+}}$ decay width in the [Lc2940 decay file](https://gitlab.cern.ch/lhcb-datapkg/Gen/DecFiles/-/blob/v32r9/dkfiles/Lb_Lc2940munu,Lc_D0p,D0_Kpi=LHCbAcceptance.dec) where it is set to 68 MeV when the PDG value is 20 MeV. I've fixed the mistake for my decfiles and the SL sim liason (@jnovoafe) has been informed and since there is a [production](https://its.cern.ch/jira/browse/LHCBGAUSS-2717) of this mode in the bk, I have not fixed the mistake at this point in time.
