Hoi Daniele, > here is that I am not perfectly sure of the generated ratioBR > since BR(b->ulnu) changed a lot in the releases 8.6, 8.8. ,10.- SP3 contains only MC produced with 8.8.0x. This is the result of grepping our tcl files, and furthermore is also stated in http://www.slac.stanford.edu/BFROOT/www/Physics/SimProd/SP3_summary.html which I would not believe just so, but after grep'ing seems to be consistent. The disentanglement of the different DECAY.DEC files will follow RSN. Cheers, --U.
