*Figure 2:* Probability of including the second muon from J/&#968; decays !RoI as a function of the extended !RoI size for different samples. Open squares are from J/&#968; decays where one muon has %pt%>6 GeV and the other %pt%>3 GeV. Full squares are from J/&#968; decays where one muon has %pt%>4 GeV and the other %pt%>2.5 GeV.
