Dear Jens Jørgen and collaborators, I have a few comments on the draft. Title: In my personal opinion, the title is somewhat too provocative. When readers see a title "Role of partonic collisions in the ....", which sounds almost like a theoretical paper, they naturally expect to get an answer to the question of "what is a role of partonic collision?" But I think our results don't/can't give an answer to the question as we said in the text. At the summary/conclusion it reads " we find good consistency with the gluon saturation model, .... but the data can be equally well reproduced by other models not requiring saturation effect..." In that case, do we still want to put the "big" question in the title? There are a few wrong statements: - page 3: "The BRAHMS experiment consists of ... for measuring exclusive charged particle..." We measure inclusive and semi-inclusive spectra, but certainly can't measure exclusive particle spectra. - page 4: "Particle densities are deduced from the observed energy loss in the SiMA and TMA elements..." We only use SiMA for the particle density measurements. TMA is only used for the centrality determination. - page6: "...but on the number of binary parton collisions..." Ncoll is expected to scale with hard collisions but it is number of binary nucleon-nucleon collisions.
