For hadronization, the weight for the non-res will be the same as the default 
setup - you just need to use the proper weightfile from Dominique.  For the 
exclusive mode studies, this weight (factor k above) will need to be 
recomputed along with using the proper weightfile from Dom.  The numbers N_h, 
N_r, and (BF^SP_res+BF^SP_nonres) will all be fixed - only BF^NEW_nonres (i 
think that's the number - i don't have my notes in front of me right now) 
will be different when varying exclusive BFs.  Whoever computed the CM2 
weights should know those numbers and can give them to Wolfgang.
