Centrality dependence (expressed in terms of average number of participants) of prompt $\jpsi$ $\RAA$ measured by ALICE in Pb-Pb collisions at $\snn$ = 5.02 TeV in the transverse momentum interval 1.5 $< \pt <$ 10 GeV/$c$. Results are compared with the BT model by Zhuang {\it et al.} . Error bars and boxes represent statistical and uncorrelated systematic uncertainties, respectively. Shaded bands represent model uncertainties. The global uncertainty is shown around unity.
