Model comparisons for average D meson $v_2$ in the 30-50% centrality class (top), average D meson $\RAA$ in the 0-20% centrality class (middle), $\Dzero$ $\RAA$ in-plane and out-of-plane in the 30-50% centrality class (bottom). The seven model calculations are described in the text: WHDG rad+coll, POWLANG, Cao, Qin, Bass, MC@sHQ+EPOS, Coll+Rad(LPM), BAMPS, TAMU elastic, UrQMD. The models WHDG rad+coll, POWLANG, TAMU elastic and UrQMD are shown by two lines that represent their uncertainty.
