The supplements provided by the authors to the reviews are detailed and thorough. Once the authors have incorporated these into a new version of the manuscript, I think an editor review of the full updated manuscript will be sufficient.

Dear authors,
First of all, apologies for the long delay in the handling of your manuscript. Due to circumstances, the editor who was handling the manuscript is currently not able to take the necessary action. I have therefore taken over.
Please provide a revised manuscript in which you address the reviewer comments, as well as a response letter with point-by-point answers to the reivewer comments. The manuscript will then be re-evaluated by at least 1 reviewer.
Kind regards
Sara Vicca
