[CIG-SEISMO] Time series as input

[masson]

Hi Stephen,

We also wrote a paper on that, as for now, I am using a modified 
version Specfem Globe (that is computing/compressing the external/global 
wavefield) for the global and our Regional code RegSEM  for the local. I 
plan to interface with the Axisem (3D seismograms in a 1D Earth Model) 
code too sometime soon. You can download the paper and a movie showing 
how this works here :

I hope this helps,

Yder
