J/$\psi$ $\raa$ as a function of $\langle N_\mathrm{part} \rangle$ for 3 $p_{\mathrm T}$ ranges in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV. See text for details on uncertainties. When assuming full transverse polarization of the J/$\psi$ in Pb-Pb collisions, as expected if J/$\psi$ are coherently photoproduced, the $\raa$ values increase by about 21$\%$ in the range 0 $< p_{\mathrm T} < $ 0.3 GeV/$c$.
