Dear Authors,

Thank you for the revised manuscript.

Before proceeding with a decision, I would like to ask you to not only address the reviewers' comments in your reply to them, but also add relevant text in the manuscript (and refer to it in your new reply). Right now, you have made changes in the text only for few of their questions. I certainly acknowledge that not all questions deserve a change in the manuscript, and some others are out of scope of your study, but there are many that do need to have some changes made in the text. This includes many of the comments of both reviewers, including the three major comments of reviewer 2.

Thank you in advance,
Kostas Tsigaridis
