Title of program: RCMBLN Catalogue Id: AAEG_v1_0 Nature of problem The interpretation of radio recombination lines is of importance to radio astronomy. The computer program described in this paper calculates the intensities and profiles of hydrogen and helium radio recombination lines emitted by a thermal source. The electron temperature is assumed to be constant throughout the source,while the electron density is a known function of position. Spherical or plane parallel symmetry is assumed in the program. The theory of the method used is described in detail by ...
