Given the comments from the reviewers and the amount of changes suggested, I would like to ask the authors to submit a second version with major revisions, although I assume they have already prepared one, or are close to completing it.

Neither of the reviewers seems to have significant problems with the science in general, and the authors should take heart from this. It appears that they have responded to all questions, comments and corrections from the reviewers, so I won't list anything here myself.

I would be grateful if the reviewers could review the revised manuscript when it is made available. I look forward to seeing the manuscript which will hopefully address all the scientific comments and the large number of comments related to presentation.

Both referees now agree that the manuscript has been improved significantly and that we can now proceed towards publication, subject to minor corrections. The latest manuscript does indeed appear to be much easier to follow.

I would like to ask the authors to include a separate, complete list of all the modifications made at the request of the referees, and for each modification, indicate the page and line in their newly corrected manuscript.

The authors have addressed all items brought up by the reviewers. I myself have included a very small list of recommended changes, none of which are major. I am sure the authors can deal with these very quickly, as they see fit. There should not be any further need to review the manuscript. I look forward to seeing the final, official paper.
