Besides editorial comments (plus typos, missing info etc etc) there are a few suggestions for the analysis that are worthwhile listing. These are not meant for this review, but we should work on them in parallel: * check if replacing mm2 with emiss-pmiss is beneficial * measure Br(b->clnu) * unfold mx to mxtrue and get the partial (Mxtrue>??) b->uln BF (useful to theorists) * redo some sys: mes (take correlations into account) , binning effect(old), Bsys (vary D*lnu more generously) *look at data-MC agreement for events in 1.5<Mx<1.6 GeV * muon sys including 2002 The other requested changes will be implemented in the version that will be sent to the referees. ciao ric
