$v_2^{\rm J/\psi}\{{\rm 2,sub}\}$ in bins of $p_{\rm T}^{\rm J/\psi}$ for p--Pb (left panels)and Pb--p (right panels) collisions at $\sqrt{s_{\rm NN}}$ $=$ 5.02 TeV (top panels) and 8.16 TeV (bottom panels) The results are compared to the$v_2^{\rm J/\psi}\{{\rm EP}\}$ coefficients measured in central Pb--Pb collisions at $\sqrt{s_{\rm NN}}$ $=$ 5.02TeV in forward rapidity using event plane (EP) based methods . The statisticaland uncorrelated systematic uncertainties are represented by lines and boxes, respectively. The quoted globalsystematic uncertainties correspond to the combined statistical and systematic uncertaintiesof the measured $v_2^{\rm tracklet}\{{\rm 2,sub}\}$ coefficient.
