Hydrogen emission & recombination coefficients with kappa electron distribution

This list provides an extensive data set for the emission and total recombination coefficients of hydrogen and total recombination coefficients to the 2s two-photon transitions with a kappa electron energy distribution rather than the more traditional Maxwell-Boltzmann distribution. The data are mainly relevant to thin and relatively cold plasma found in planetary nebulae and H II regions. The data set is complementary to previous data sets provided by Hummer and Storey and Storey and Hummer under a Maxwell-Boltzmann distribution assumption based on thermodynamic equilibrium. The data set is structured as a function of electron number density, temperature and kappa. An interactive fortran 77 and C++ data servers are also provided as an accessory to probe the data and obtain Lagrange-interpolated values in all three variables between the explicitly given values.
