ObsPy (seismological observatories) has a cwt module and "for now only 'morlet' is implemented" pyCWT has Morlet wavelet; Wavelet transform 3D plot for CoP. This model is then revised, especially the uppermost few hundred meters, based on results from a study of S to P converted waves from shallow interfaces beneath various stations, from the traditional Wadati plots analysis, and from the interpretation of two short seismic reflection/refraction profiles. The program graphically plots transmissivity as a function of these factors so that the user can visually estimate their relative importance in a particular application.
