Detailed Description

Equation of state for the 2010 CompStar school.

General tabulated EOS, reading a table passed as an argument to the constructor. When built with Eos::eos_from_file(), the file must contain the following lines: 

17	Type of the EOS 
/full/path/to/the/eos/table/name_of_the_table.d 
/full/path/to/the/eos/table/name_of_the_table.d

(Note the two identical lines).

ent [input, unit: $c^2$] log-enthalpy H defined by $H = c^2 \ln\left( {e+p \over m_B c^2 n} \right) $, where e is the (total) energy density, p the pressure, n the baryon density, and $m_B$ the baryon mass
nzet number of domains where the baryon density is to be computed.
l_min index of the innermost domain is which the baryon density is to be computed [default value: 0]; the baryon density is computed only in domains whose indices are in [l_min,l_min+nzet-1] . In the other domains, it is set to zero.
par possible extra parameters of the EOS
Returns:
baryon density [unit: $n_{\rm nuc} := 0.1 \ {\rm fm}^{-3}$]
