Hi all, I produced a new page with the comparison data-mc with the correct sideband subtraction (in each bin of the plotted variable). http://www.slac.stanford.edu/~daniele/vub/complots/comp.html This is my first set of comments: 1) in general the agreement is better in the generic MC with respect to to Cocktail. 2) the disagreement is the charged and neutral multiplicities. In particular the neutral multiplicity seems to be a bit worse in the high-energy case (160MeV<E<320MeV, E>320MeV). This affects mm2 and mx distributions. 3) if we normalize using the number of reconstructed B's we observe that cocktail and generic MC's go in different direction (don't look at the chi^2 in these plots since it is wrong). This effect is also reflected in the efficiency comparisons. We must study in detail this point. Daniele
