Top panel: non-prompt $\rm D^0$-meson $\pt$-differential production yields in \PbPb{} collisions at \fivenn{} in the 0--10\% and 30--50\% centrality classes. The pp reference spectra, $\av{T_{\rm AA}}\times{\rm d}\sigma_{\rm pp}/{\rm d}\pt$~, are also shown Middle and bottom panels: $\pT$-differential $\RAA$ in the \cent{0}{10} (middle) and \cent{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.
