Left: Coherent \jpsi cross section as a function of $\langle \Npart \rangle$ in \PbPb collisions at \fivenn 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 {\em et al.}~, Gay-Ducati {\em et al.}~(GBW S2/S3 and IIM S2/S3)~ and Cepila {\em et al.}~(GG-hs)~. For the interval 70--90\%, the calculations from W. Zha {\em et al.} and IIM S2 are shifted on the x-axis for visibility. Right: Coherent \jpsi 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 $\Delta C$.
