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

<br>
Following plots are for tracks which has matching mc particles. <br>
Do we cut on these? such as
<pre>
     d0 < 1.5 mm
     z0 sinTheta < 1.5mm (this cut may be problematic)
     prob > 0.55
     nBLHits >= 1
     nPixHits >= 1
     nSCTHits >= 6
</pre>
