Surface wave ray tracing and azimuthal anisotropy: a generalized spherical harmonic approach
We explain in detail how azimuthally anisotropic maps of surface wave phase velocity can be parametrized in terms of generalized spherical harmonic functions, and why this approach is preferable to others; most importantly, generalized spherical harmonics are the only basis functions adequate to des...
