Thank you for this important paper of which the scientific community will profit. Nevertheless, both reviewers have recommended a "thorough" or "substantial" revision, so I would like to suggest a major revision of the manuscript, according to the thorough comments of both reviewers. You have already responded to the reviewer´s comments in a very good way so that I would like to encourage you to re-submit a revised manuscript.

Thank you for a greatly improved manuscriüpt. However, both reviewers have marked the need for further, minor improvements which they have specified in their reviews. The authors are kindly asked to take these suggested changes into account. After this, a publication will be pursued.
