Hi, some small feedbcak on BAD 582 (I would like to read it better, but since this is not going outside I think the structure is good enough): 1. section 2.1 I think that most papers quote 88M events 2. section 3.1: the definition of deltaE and Mes are incorrect (mes=sqrt(S/4-p*^2); deltaE=E*-sqrt(S)/2) 3. section 3.3 the prmm2 cut cuts away 68% of the D*lnu events that surive all other cuts 4. section 3.3 the Ks efficiency (see Marcella's presentations) is about 80% [I would not quote an error because it depends on the spectrum] 5. end of section 3.3: did we switch the definition of eps_u and eps_mx? are the numbers there correct? 6. section 4, third to last paragraph. I do not think it is useful to mention again the meaning and value eps_u. I would only quote eps_mc at this point, but I would not say that it depends only on theo input. 7. sec 4, last paragraph. I think this would be a good spot to quote the B0 and Bch BRBR separately 8. fig 3: I would remove the first figure (and I guess you are away that fig 2 is promising one plot more than currently available. As far as further plots are concerned, I can immagine that (after the coll wide circulation) we should redo the total error vs Mx , in order to show the individual error contributions. I would also like to have the fit result for B0 and Bch separately (the level of background is different) In a presentation I would also like to show the result in terms of p*,Q^2 and also neutral and charged multiplicity (I think we need to make these plots). Finally it would be nice to see the equivalent of the middle plot of fig3 before any cut, in order to illustrate the experimental challenge bye ric
