Hi all, I prepared and committed the new chains in order to create the files used by the fit as signal and background model. Actually the situation is not so bad as I described it in the last meeting as far as the MC statistics is concerned. Mixing properly generic and cocktail we can get 270 fb-1 of equivant statistics. The proper mixture satisfies: - NB0/Bch is the same of data - Ndstar/Ntot, Ndc/Ntot,... is the ~ same of data and in preparing the mixture - SP3 is used to model run1, SP4run1 + SP4run2 to model run2 (after comparing agreement of all the variables) - generic and cocktail are equivalent and then merged without any weighting I put the new files in the usual area (/nfs/farm/babar/AWG7/ISL/tmp/rootfitfiles/) The detailed information about yields and composition of the merged files are in http://www.slac.stanford.edu/BFROOT//www/Physics/Analysis/AWG/InclusiveSL/islrec$ Daniele
