Charge reco efficiency is defined as the ratio of # of generated electrons to # of reco tracks w/
* nFitP>=5, including vertex as a hit
* delPhi<3 mrad
* delTheta <3 mrad
* the sign of the reco charge is correct
Note, 3 mrad translates to 1cm displacement of reco track vs. projected ideal helix at the Endcap SMD plane (Z~300cm).
No cut on reco pT is imposed.
