I estimate that the number of J/Psi is 30% too high for sets 1,2 and 4 ** not allowing axial only track matches to muons. *** not allowing axial only tracks and only allowing nseg=3 muons **** allowing axial only and nseg>1 muons ***** vertexing with latest d0root_btag code. % allowing nseg>=0 muons Events reprocessed with AA # J/Psi set 1 3960 set 2 7320 set 3 7000 set 4 10330 set 5 12420
