Run14 Au+Au 200 GeV 0-10% minimum bias event.

Tracks shown are HFT matched only. Only BEMC towers matched to at least one HFT track are displayed. The electron track is selected with all PID (TPC+TOF+BEMC+Likelihood) selections, has pT=2.5 GeV/c, and has a 3D log(DCA) within -2 to -1, corresponding to a probability of being a true b->e decay > 75%.
