H I lines
The following table lists air wavelengths*1 (in angstrom) and Case
B intensities (for Ne=10 000 K, Te=10 000
cm¯³, relative to H beta) for the recombination lines of
atomic hydrogen. Wavelengths are from Astrophysical Formulae
(Lang, 3rd edition); line intensities are from Hummer
& Storey (1987; MNRAS 224, 801).
