Solar models

The model provided here has been used fairly extensively as a reference for helioseismic inversion. It is commonly known as Model S, and described by Christensen-Dalsgaard et al. (1996). Briefly, the model uses OPAL equation of state and opacity, and includes settling of helium and heavy elements.

The model is presented in two forms. One contains a basic set of variables, which may be sufficient for many purposes. The second is a rather complete set (the so-called GONG form), documented in a separate note which is also avaiable.
