Hi all,
I reoptimized the cut on the purity (since the selection is changed and
the full dataset is available). The stat. significance as a function of
the cut on the purity (all analysis cuts applied) is in:

Dc

D0

The optimal values now are
- D* ipur > 24%
- Dc ipur > 9%
- D*0 ipur > 8%
- D0 ipur > 9%
before they were
- D* ipur > 14%
- Dc ipur > 6.5%
- D*0 ipur > 5%
- D0 ipur > 6%
I propose to apply these new cuts. The yields will be 15-20% lower with a
large gain in purity and in the number of selected events.
If you agree, I will commit the new cuts.
