Hello folks, I have added in the BAD (among other things including the new PID from Urs) a piece on Q=0: section 6.15 in http://www.slac.stanford.edu/~rfaccini/phys/vub/paper.ps (in the HEAD of the BAD). Please check you like the flavour of it or suggest changes to it. I still have to add hte MC and toyMC studies performed today. goodnight Ric
