[CIG-SEISMO] problem to read external velocity model

[Obermann Anne Christine]

Dear Specfem developers,

Using the new version of SPECFEM2D Cartesian 7.0, we encounter a problem reading an external velocity model.
Attached, we send you two files, OLD_Model worked well with the older specfem releases (6.1) and the NEW_Model is an example we found for the new version on your site. The structure of the files is apparently different.

We have trouble understanding the NEW_Model structure. The counter on the left is interrupted at several occasions (1:25, followed by 5 etc). Could you please let us know what this column represents?

Which option do we have to choose in the Par_file? (external or legacy?)

Thank you very much!
Anne and Pilar
