M-C Event Samples Available   

1. General  setup, assumptions
   1. use UPGR13 geometry
   2. run in SL07e
   3. use PPV vertex finder in reco
   4. displace & smear vertex in GEANT in X-Y plane: x0=+1mm, sig=200us, y0=-2mm, sig=200um (except setA)
   5. beam energy sqrt(s)=500 GeV
   6. detectors passed by track thrown at various eta at 3 Z-vertex location of -60, -30 an 0 cm.
