Top panel: non-prompt $\rm D^0$-meson $\pt$-differential production yields in Pb$-$Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV in the 0$-$10% and 30$-$50% centrality classes. The pp reference spectra, $\left\langle T_{\rm AA} \right\rangle \times{\rm d}\sigma_{\rm pp}/{\rm d}{p_{\rm T}}$, are also shown. Middle and bottom panels: $\pT$-differential $\RAA$ in the 0$-$10% (middle) and 30$-$50% (bottom) centrality classes, compared with model predictions. Open markers indicate the points for which the pp reference is extrapolated (see text). Vertical bars, empty boxes, and the shaded box around $\RAA=1$ represent the statistical, systematic, and normalisation uncertainty, respectively.
