 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)
