Inbuilt models

Inbuilt models

Most users of SeisModels will probably want to simply calculate properties for one of the inbuilt models of the Earth and moon. They are:

AK135

1-D layered model of the Earth, containing density.

IASP91

1-D model of velocity.

N.B. iasp91 does not contain density.

This version of the model uses the original coefficients and is a PREMPolyModel as published. Other implementations available may use a layered piecewise linear model and/or add density from other sources.
