Figure 8

 Average $\RAA$ of $\Dzero$, $\Dplus$ and $\Dstar$ mesons compared with model calculations. The three rows refer to the 0--10\%, 30--50\% and 60--80\% centrality classes. The left panels show models based on heavy-quark transport, while the right panels show models based on pQCD energy loss. Model nomenclature and references:BAMPS~, CUJET3.0~,Djordjevic~,LBT~,MC@sHQ+EPOS2~,PHSD~ POWLANG~, SCET~,TAMU~ Some of the models are presented with two lines with the same style and colour, which encompass the model uncertainty band.
