evaluation of Bates minB sample (Jan)

Evaluation of minB events ample produced by Mike at Bates in January of 2008.

Events characteristic: Pythia MinB events, sqrt(s)=500 GeV, vertex Gauss(0,60cm)

Below you see detectors acquired by e+/e- surrogate :  

  1st pi-,pi+ with pT>2.0 GeV and eta>0.7

FGT disks are located at Z of 70,80,...,110 cm - our best guess location.

3 events samples were chosen based on Geant vertex location of -60, 30, and 0 cm, with margin of +/-10 cm, what leads to smeared FGT disks.
