- There are several new features which reduce the usability of this study, but it is still interesting as a general overview.
- There is a factor of two missing in some of the Afs equations. This was fixed in the latest afs presentations.
- It has been shown that the production asymmetry does not matter for Afs^s, by Stone et al, since it is washed out by the fast oscillations.
- Cross-talk backgrounds of D+ and Ds from other B-decays were not considered at that time
- A single resolution was assumed, we now know the resolution depends heavily on the proper time
- Since the k-factor depends on the Dmu mass, we cannot fit simultaneously in time and Dmu mass without having a Punzi term, maybe 2D. We have abandoned that approach, instead we fit 2D in KKpi and proper time, which means some of the B-peaking backgrounds are not fit explicitly, they are simply part of the signal fit
