Figure Caption

Here the invariant mass spectra for each pT bin are shown.

For each pT bin, the larger plot displays the invariant mass and corresponding fits for J/ψ and ψ(2S) based on the invariant mass spectrum (reported with empty black markers), after subtracting the mixed-event background (reported with empty orange markers).

The smaller plot is a zoom on the ψ(2S) peak.
