Hi all, we should check this also in our run4 ntuples. Henning, could you just look at mes fits for pure modes (D*pi) and compare run 1-3 with run4? Same for deltaE.

Hi, There was a significant although small change of Mes over run4. I gave a presenation to the BaBar-PEPII liason group about this. The data is very inconsistent and does not suggest either the beam energies were wrong or were recored wrongly. This becomes confusing.
