The opposite-sign invariant mass spectrum of mass pairs, for the four transverse momentum intervals used in the data analysis, after mixed-event background subtraction. The kinematic domain is $2.54$ and the centrality interval is 0--90\%. The result of one among the 60 $\chi^2$ minimization fit is reported, corresponding to a CB function for the signal, a variable-width Gaussian for the background, a $2
