Comments for breco
1) we have a gain with respect to the old production ~25-30%. It seems to
be less than the one I quoted in the previous postings. This is due to
the lower yields (after the lepton cuts) in the most recent production
(see the correspondent history plot).
Since for B->Dpi the time dependence is flat probably the lepton id
was either more efficient or less pure in the first 8 fb-1
2) A reoptimization of the cut on the purity has to be redone and perhaps
also the int purity tables. Moreover we are reconstructing modes of
superblock 4 (they should not be present in the skim) as you can see
from this plot
http://www.slac.stanford.edu/~daniele/vub/comp10pur.ps
top plot: ~all cuts applied, cut on single mode purity of 10%
bottom plot: same but no cut onsingle mode purity)
3) generic MC and data are close now.

Comments for the comparisons:
1) data-MC comparison is bad for B0 in the depleted sample. In particular
look at the pstar spectrum, nneutral and MX.
2) data-MC comparison is good for ChB (but the stat is still low).
The well known mm2 problem seems to be still there
3) comparison data old-new show again problems for B0's (depleted sample)
4) the generic MC did not change. Probably the resolution seems to bit
better (but here we have only SP4 MC)
