\jpsi \meanpt extraction in \PbPb collisions at \fivenn at midrapidity for the 0--5\% (left panel) and the 70--90\% (right panel) centrality interval. The data points correspond to opposite-sign \ee pairs from the same event, the blue line to the \ee pairs from mixed events, and the red line is the combined fit that includes the mixed events and residual background which is described by the polynomial function.
