Reviewer #3 has raised a number of further points, particularly including possible errors in equations, and their possible consequences for the described numerical experiments. There are also requests for clarification in details regarding the numerical experiments.

Note also the further comments from reviewer #1.

Reviews have been supportive of publication, but I would ask you to please note the additional reviewer comments. In particular you should check equations carefully for remaining inconsistencies or sign errors. As indicated by the reviewer there are possible implications for the results, if these are implementation (rather than typographical) errors.

Please could you add an "Author Contribution" section to this paper, as described in the manuscript preparation guidelines.

Typos: "are rule" (abstract), "whos" (below equation 3), "it's" in place of "its"

The final sentence of the "Author Contribution" section does not seem to be grammatically correct, but otherwise I am happy to proceed to publication.
