pynucastro.eos.degeneracy_parameter_bounds module# A coarse table of degeneracy parameter (eta) for use in bracketing the root finding algorithm. pynucastro.eos.degeneracy_parameter_bounds.get_eta_bounds(rhoYe0, T0, include_positrons=True)[source]# Return an interval that we expect to contain the degeneracy parameter, eta, given a rho * Ye and T Parameters: rhoYe0 (float) – the electron mass fraction (rho * Ye) T (float) – the temperature (K) Return type: tuple(float, float)
