v2{EP} of $J/\psi$ at forward rapidity in Pb–Pb collisions at $\sqrt{s_{\mathrm{NN}} }  = 5.02$ TeV in semi-central collisions 
-->Scaled by the number of heavy quarks (v_{2} divided by 2 for J/psi) for comparison with D mesons

J/psi->mumu : 20-40% centrality with SPD  as EP detectors and dimuon <cos(2\Delta\phi)> extraction method. Boxes contain systematics on signal extraction and $J/\psi$ reconstruction efficiency. Global uncertainty comes from event plane determination and resolution

arxiv ref : 1709.05260

D mesons : 30-50% centrality, arXiv:1707.01005
