Lett.. https://doi.org/10.1785/0220240047 Velocity models 6 velocity models are available, for both P- and S-wave velocities. Model extenion is roughly 8° of latitude with 4° overlap between models. Grid cells are cubes of 4 km. Velocity models are identified by their (rough) latitude range: for example, 18_26 indicates the model extanding from 18°S to (almost) 26°S. Models are distributed in NonLinLoc format (Lomax, 2000 ; see http://alomax.free.fr/nlloc/ for details and usage).
