Hi all,

 these are the plots for the pstar spectrum for b->ulnu events on data.
A cut on Mx<1.55 Gev is applied.

 My general comment is that the spectrum seems to be softer than expected
for all subsamples.
For instance compare with the result on generic MC.

This could be the reason why the the fitted value goes down once the cut
on the pstar cut is tightened.
