Hi,

 I took the ntuples produced on run2 by me (Dstar) and Giancarlo (D0).
The result is very promising. In

    SemiExcl/dstar_run1122/mainB0Dstar.html

you find the results for Dstar on 3.1 fb-1. We get ~1500 events with a
purity of 50%. The yield is ~20% more than run1. The tail in the mes peak
seems also to be less pronounced.

the ones for the D0 on 1 fb-1. We need more statistics but the yields
and purities seem compatible with the run1.
