After last update Hazel crashed

[Jose Iván]

After I updated today the Hazel2 repository, I got an error and it is not possible to invert a single pixel.

Yes, I have recently added the macroscopic velocity as a parameter in photosphere. You would need to add "vmac" in all photospheric models and add nodes and ranges for vmac in the configuration file.

[Jose Iván]

You are right, I already changed it in the model, but not in the configuration file. Thanks
