The $z_{\rm g}$ distribution of prompt $\Dzero$-tagged jets compared to that of inclusive jets for $15 \leq p_{\rm T}^{\rm jet\,ch} \leq 30$ GeV/$c$ in pp collisions at $\sqrt{s}$ = 13 TeV, normalised to the total number of jets. Model/data ratios are shown in the bottom panels for PYTHIA 8  and POWHEG  + PYTHIA 6  simulations.
