Tracking Reconstruction Efficiency Study

Efficiency = (Number of mc particles with a matching reco track)/(Number of me particles)
Matching was done by barcode.

*Efficiency plots:


Following plots are for tracks which has matching mc particles.
Do we cut on these? such as

     d0 < 1.5 mm
     z0 sinTheta < 1.5mm (this cut may be problematic)
     prob > 0.55
     nBLHits >= 1
     nPixHits >= 1
     nSCTHits >= 6
