Hi Dave,

I use the default error estimation for TEfficiency class, which is the frequentist estimation with Clopper-Pearson interval. Zooming in on all of the plots, all the error bars to efficiencies are within [0,1] range. It's probably some of the plots having the upper bound at 1.0. I've updated those plots such that the y range goes up to 1.05.  

To Ming,

The distribution of number of tracks (within MVTX acceptance and true pt >0.5GeV/c) has been added at the end.

Hi Sookhyun,

Nice work!  Should I understand "efficiency" in these plots in the usual
sense of eff. ∈ [0,1]?  The reason I ask is that the error bars seem to
go above one, so I'm wondering if you're calculating binomial errors.

Cheers,
Dave
