Why is this less than 1 sigma?
Both numbers are highly correlated, right?

Hm, I'm not fully convinced that this explain
whole the difference. The one-bin unfolding
certainly also depends on the dFN model.

Virginia: do you know by how much this result
changes when changing mb and a within the
CLEO or Belle SF parameter uncertainties?
