A Python package for surface wave tomography and receiver function analysis. This is an all-in-one package which includes several functions:
- Data request for earthquake surface wave waveforms, teleseismic P wave (receiver function), continous waveforms (for ambient noise)
- Ambient noise cross-correlation (two-station ambient noise interferometry)
- Three-station ambient noise interferometry
- Surface wave dispersion measurements (aftan)
- Receiver function (rf) computation and harmonic stripping
- Surface wave tomography (ray-based tomography and eikonal/Helmholtz tomography)
- Bayesian Monte Carlo inversion(1. isotropic inversion using rf and Rayleigh wave; 2. VTI inversion using rf, Rayleigh waves and Love waves)
- A least-square inversion for azimuthally anisotropic Vs model
