Add phase amplitude calculator

[sebmagia]

Hello,

Can a feature be added that computes the phase amplitude for the pickers? PhaseNet's original implementation does it; I don't know about the other pickers.

Kind regards,

Sebastian

Hi @sebmagia ,

thanks for the suggestion. As you've spotted, this is currently not implemented in SeisBench. The reason for omitting this from the models themselves it that it adds a requirement for instrument response information. In addition, amplitude extraction is sensitive to parameter settings, such as the band to select from or the components. However, it could be implemented as an additional class or function to post-process the picks.

Asides the response removal and appropriate filtering, extracting amplitudes is rather straightforward once you have the picks. It should be rather quick to code up for users.

Nonetheless, I'll leave this issue open as a feature request.
