Hi all,

 these are the numbers I got applying the reweighting based on the breco
composition, the pstar and the missing mass squared.

 Conclusions:


 * All the effects are systematically 50%-60% higher for Q1 than Q0. This is
   going in a direction that makes sense. I hope that also the other
   sytematics will show this

 * Breco reweighting has a pretty large effect. You have to consider that

   1) the weight are here very different from 1 (since the purity of the data
      and the cocktail one is very different) and we are not taking into
      account the large change in the error due to MC statistics.

   2) since the low purity modes are coming from generic MC and since their
      weights is higer and far from one, we are getting the value we
      obtained using the generic MC as a model

 * Pstar reweighting: negligible effect

 * MM2: pretty large effect. We have a differences around 13%. We quote 8.5%
   in the BAD. Here the weights are large too. I think that if we take into
   account the correct MC stat error this difference is within our estimation
   of the syst error.
