Hello Peter, --> http://www-f9.ijs.si/~krizan/herab/open_charm/paper/paper-v5.1.ps. --> Let us know within a week if you have any further comments to this final --> version. Many congratulations on finishing this analysis and finally getting the paper publication-ready! I have a few minor comments which you might want to take into account: - page 6, 1st paragraph, 7th line from bottom: Something is missing after "... and x_b was assumed to be" --> A % sign sneeked in and commented the rest of the line... - page 6, eq. (7) "p" is used for "proton" or "momentum" in other parts of the paper. Why don't you call the weights "w_i" or something like that? --> done - page 9, left column, first complete paragraph: You write down the equation for P_V with two division signs, like A/B/C ; this is ambiguous and should be avoided: do you mean A / (B/C), i.e effectively (A*C) / B, or (A/B)/C, i.e. A / (B*C)? --> done - page 9, left column, second complete paragraph, and page 10, 3rd paragraph of the Summary: Would you expect this ratio to be the same in e+e- and pA collisions? Your text suggests that you expect agreement. If you don't have any expectation, I would just quote the e+e- value for comparison and let the reader draw their own conclusion. --> Very far from threshold the hadronisation should not depend on how the --> quark was produced, but then we should see no leading-to-non-leading --> particle differences. Indeed, you are right, so I have corrected as --> you suggested. - Tables 6 and 7: Be consistent in typesetting the "b" for barns in upright font also in "\mu b" --> done - Typo in section title of "Acknowlegdments". --> done - References: [almost all] you are missing a full stop after "al", and a comma between the authors and the journal titles [11] - [14] The author should be I. Abt et al. (HERA-B Collaboration) [14] has two dates: 2007 and (2006) --> There was a mess with the references because we have been using a --> wrong style file along with the wrong example, and some remnants of the old --> style remained on several places.
