Model S20RTS is a shear velocity model of the mantle derived using normal splitting, surface wave dispersion, and body wave travel time data. The most recent description of this model is given in the paper: Seismic imaging of structural heterogeneity in Earth's mantle: Evidence for large-scale mantle flow Jeroen Ritsema and Hendrik-Jan van Heijst Science Progress, 83, 243-259, 2000.
