test_zmodel

Doublecheck codes read correctly the 3D velocity model of Zhu et al., 2015). + IASP91

Issue reported from DK and GH.

Potential issues: - Are the Vp and Vs values in the model changed during the scan?

We can check this by plotting the vp and vs values along the same line and then we can see how it goes.

Some depth value might be missing in the model and this “squeezes” the migration, because we almost see that the depth scale is compressed.
The shape of the ray tracing itself is wrong for something that is probably related to velocity. This can result in the discontinuity red spots not being connected, the discontinuity being thick.
