COMMENTS
Evolution of the effective number of relativistic degrees of freedom contributing to energy density, g(*), can be seen on a graph as a function of temperature. At the energy scales below 0.1 MeV, g(*) is equal to this constant (in the Standard Model and in the minimal extension of Standard Model).
