The manuscript has been reviewed by two independent reviewers of which both are in general positive about this study. Particularly reviewer 2 has been asking for more detail and whether the data allows for more in-depth analysis.
The authors have clearly addressed the major concerns raised by both independent reviewers as well as one additional comment. With this I am inviting the authors to provide the revised manuscript for a final check before publication.

with kind regards

Dear Peter Kuhry et al.,

with kind regards
