Dear Authors,
after careful look at both referee reports and the provide public response. Both reviewers have raised important and substantial comments helping to improve the manuscript, which mainly referred to the presentation of the results. The authors provided a detailed response to the raised concerns. Thus, the manuscript is a major revision and will be again subject to a further review by the referees and the editor.

I kindly ask the authors to upload the revised manuscript and a point by point reply to the reviews. The reply to the reviewers should contain the revised manuscript with labbeled/tracked changes.

Best regards,
Gunter Stober
