The instrument in the bzip2 tarball public_nse.tbz illustrates how to put any reaction network into its NSE state. If you are going to get serious about NSE calculations, then you'll want to modify this public code to use more accurate nuclear data (e.g., ground state spins and temperature dependent partition functions), add more physics (coulomb corrections), and increase the number of isotopes. Still, the two figures below suggest the public code gives reasonable results for the assumptions made.
The movies below accompany "ProtonRich Nuclear Statistical Equilibrium". Each movie shows the isotope abundance on the vertical axis and either the temperature or electron fraction Y_{e} on the horizontal axis. Limits for the abundance vertical axes are 0.01 (i.e., major abundances only; lower limits of 10^{4} are avaliable upon request). The movies cover the temperature range 3 ≤ T_{9} ≤, density range 10^{3} to 10^{9} g cm^{3}, and Y_{e} range 0.4 to 0.6.
