Projections of a fit to the 2-dimensional invariant mass distribution for inclusive J/$\psi$ pair candidates for (a) $m_1(\mu_1^+ \mu_1^-)$ and (b) $m_2(\mu_2^+ \mu_2^-)$. The (black) markers show data. The (black) solid line represents the total fit function. The (blue and green) dashed-dotted lines indicate the background contribution from a combination of a real J/$\psi$ signal with a combinatorial candidate. The (yellow) dotted line represents muon pairs from combinatorial background.
