Left: Coherent J/$\psi$ cross section as a function of $\langle \Npart \rangle$ in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV at midrapidity. The statistical uncertainties are shown as bars, while the systematic uncertainties (excluding the global contribution from the beam luminosity) are shown as boxes. It should be noted that the interval 40-50% is half as wide as the two more peripheral ones, 50-70%, and 70-90%. Data are compared to calculations from W. Zha et al., Gay-Ducati et al. (GBW S2/S3 and IIM S2/S3) and Cepila et al. (GG-hs). For the interval 70--90\%, the calculations from W. Zha et al. and IIM S2 are shifted on the x-axis for visibility. Right: Coherent J/$\psi$ cross section as a function of $\langle \Npart \rangle$ measured at midrapidity (black markers) and forward rapidity (red markers)  normalised to the corresponding cross sections measured in the same rapidity ranges in UPC  and corrected for the centrality interval width $\Delta C$.
