The $p_{\rm T}$ dependence of $v_{\rm 2}$ for the centrality range 30--50\% in Pb--Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV. Results are shown for open and hidden charm (D-mesons and J/$\psi$), for open and hidden beauty (electrons from semi-leptonic beauty-hadron decays and $\Upsilon(1S)$), and for pions .
