Performance goals for the BaBar reconstruction.
Last updated 980401.

 (1) Electron ID efficiency (per found track, and at 1% pion mis-ID) for 
     single tracks uniformly distributed in cos(theta-lab):

         Momentum        Efficiency
         --------        ----------
         0.5 GeV         95%
         1.2             90%
         3.0             90%

 (2) Muon ID efficiency (per found track, and at 5% pion mis-ID) for single 
     tracks uniformly distributed in cos(theta-lab):

         Momentum        Efficiency
         --------        ----------
         0.5 GeV         (at threshold of efficiency)
         1.2             90%
         3.0             90%

 (3) Mass resolutions:
