Hi all, I've re-ran the data-MC comparison on newly produced files (o01 version) and here's the results: http://www.slac.stanford.edu/~asarti/recoil/devel/KLstu/urs/comparison5mxminpileptoncuts.ps to be compared with the old one (no reweghting): http://www.slac.stanford.edu/~asarti/recoil/devel/KLstu/nu/comparison5mxminpileptoncuts.ps and the other old one (with reweighting) http://www.slac.stanford.edu/~asarti/recoil/devel/KLstu/nurew/comparison5mxminpileptoncuts.ps The net effect seems smaller than that one expected. The usual cuts (likelihood > 0) and prmm2 cut >-3 are applied. Let me know if any further check is needed. alessio ______________________________________________________ Alessio Sarti Universita' & I.N.F.N.
