Title of program: SELECT BN,CN VALUES Catalogue Id: AAEH_v1_0 Nature of problem The departure coefficients from thermodynamic equilibrium, bn, and their derivatives, cn, are required for the computation of intensities and profiles of hydrogen recombination lines from thermal radioastronomical sources. These coefficients have been computed by Brocklehurst(1970) for values of n up to 300, for 6 values of electron temperature, and for 8 values of electron density. As it is not expected that intensity calculations will be required for more than a few lines at a time, and as the ...
