salvus.opt.misfits.deprecated.phase_misfit

salvus.opt.misfits.deprecated.phase_misfit salvus opt misfits deprecated phase_misfit
Deprecated implementation of the phase misfit.
This one does compute the correct misfit and adjoint source but does not have sophisticated frequency filtering and thresholding operations so the results can sometimes be a bit unexpected.

Functions

phase_misfit_and_adjoint_source()

Compute the phase misfit and adjoint source.
