Comment on 'Crustal thickness across the Trans-European Suture Zone from ambient noise autocorrelations' by G. Becker and B. Knapmeyer-Endrun

The methods advocated by the authors in their recent publication seem quite powerful and useful innovations in the methods used to process ambient noise data. However, insufficient details are given in the descriptions of the methods used to reproduce the results shown in the paper. In the hope that others may not pursue processing dead ends, I summarize my own attempts to reproduce the details of their study and suggest what additional methodological details could be provided to make the results more robust and reproducible.
