$p_T$ dependence of $J/\psi$ $v_2$ in pp collisions at 13 TeV
Data points are obtained following the procedure detailed in the AN and the p-Pb analysis (Phys. Lett. B 780 (2018) 7-20)
The non-flow suppression is done through either yield subtraction or through template fit
No significant $p_T$ dependence is observed. Integrated-$p_T$ elliptic flow is compatible with 0.
