After having assessed the Reviewers' comments and the Authors' replies to these, I am willing to give the authors the opportunity to revise their work. The set of revisions required is moderate to major and, in case the authors decide to revise their work, the manuscript will be subject to an additional round of reviews. It should be clear that in case the outcome of this additional round of reviews is in the direction of major revisions, then the manuscript will be released.

I have now received the comments of the two reviewers who were involved in the analysis of the work. While one of them is satisfied with the way the authors have addressed his/her concerns, Reviewer No. 2 still raises a critical point. The same point was also raised in the context of the previous revision. I do believe addressing it to the full satisfaction of the authors and of the reviewer to be of utmost importance. As such, I am recommending a set of major revisions, which mainly revolve around this point, to give the author some time to properly and fully explore the issue. It is also not my intention to discount any of the other minor comments raised during this review phase.

I think the manuscript can be published in the current format, also in agreement with the referee's report.
