Hi, this is our current list of systematic errors that probably should be taken into account for the unfolded spectrum: * B -> D(*,**) l nu X branching fractions * Excl. b -> u l nu branching fractions Is there some rewweighting as for the B -> D(*,**) l nu? * m_ES Fit parameter variation * mb, lambda1 dependence How should we do this? Should we still use the reweighting how it was used? * ssbar popping At which stage and where should this be done? * Hadronization error What is meant by "Breco composition, background subtraction" in table 19? In the text it sounds like there is no error coming from the Breco composition but I cannot find anything about background subtraction. Kerstin
