Detailed Description

This class is experimental.

O2scl Does not contain the EOS, only provides some code to manipulate it. This class is designed to be used with the file which was originally called and now referred to as and stored e.g. at

In order to force the EOS to a uniform grid, linear interpolation is used to recast the variation in baryon density, choosing the grid in baryon density to be the same as the section in the table with T=0.1 MeV and $ Y_p = 0.1 $ for all temperature and proton fraction points.

The data for eos_sn_base::E, eos_sn_base::F, eos_sn_base::S, and eos_sn_base::P is not stored in the table but can be computed with eos_sn_base::compute_eg().

See also the documentation at eos_sn_base and the Finite-temperature Equation of State Tables section of the User's guide.

See Shen98 and Shen98b .

Thanks to Matthias Hempel for providing the correct temperature grid.
Add the T=0 and Ye=0 data to this class. Separate tables for these cases have been released, but I don't think this class can read them yet.
