We provide a data set of emission and recombination coefficients of hydrogen using a κ-distribution of electron energies rather than the more traditional Maxwell-Boltzmann (MB) distribution. The data are mainly relevant to thin and relatively cold plasma found in planetary nebulae and H ii regions. The data set extends the previous data sets provided by Storey and Hummer which were computed using an MB distribution. The data set, which is placed in the public domain, is structured as a function of electron number density, temperature and κ. Interactive fortran 77 and c++ data servers are also provided as an accessory to probe the data and obtain Lagrange-interpolated values for any choice of all three variables between the explicitly computed values.
