The theory used to develop the model is described in :

Xiang-Dong Li and Barbara Romanowicz , "Comparison of global waveform inversions with and without considering cross-branch modal coupling", Geophys. J. Int. (1995) 121, 695-709. (view Abstract)

The model saw16bv is a VSV model parametrized laterally in spherical harmonics up to degree 16 and radially in 16 unevenly spaced splines.
