Shouldn't there actually be a word or two about the convergence of the DTF?

you can make the assumption that the (K- K+) combine to form a D0 with a specific invariant mass. This results in a so called *mass-constraint*. In addition the two kaons should originate from exactly the same point in space. If you know that your data only contains prompt D* candidates, you can constrain them to do come from the primary vertex. Boundary conditions like those are called *vertex-constraints*.

Don't you miss a closing bracket in the last sentence?

Yeah, that's a good idea.

Thanks Laurent!
I think we can merge this, and proceed with further modifications later on.
