The sig99 routine is described in this journal paper. The routine kapfxt.f has the same physics, but also returns analytic first derivatives with respect to the temperature and density.
opacities of pure carbon |
density derivatives |
temperature derivatives |
|
sig99 test driver plus an include file: vector_kap.dek |
kapfxt test driver plus four include files: implno.dek const.dek vector_eos.dek vector_kap.dek |
To use these either routine you will need either the Helmholtz or Timmes equation of state.
