Author Response

We thank the reviewer for attentively reading the revised form of our paper. We have made further improvements of our figures and hope they are now satisfactory for the reviewer in their present form.

We have enlarged fig. 1 and increased it to 300dpi

We have added arrows to fig. 2 and have added an arrow legend in the accompanying text

We have enlarged fig. 3 to 5, the size of the fonts itself is restricted by the statistics application.

Best regards Andreas Rolf
