#include <eos_tov.h>
This implements a linear EOS with a fixed speed of sound and a fixed energy density at zero pressure. This will also compute the baryon density, if one calls set_baryon_density() to set the baryon density at one fiducial energy density.
Given a fiducial baryon density at some energy density
and pressure
, the baryon density is
