I would like to add data for the D1 hyperfine constants of the K40 and K41 isotopes with this pull request.
The data are from table III of
Falke, Stephan, et al. "Transition frequencies of the D lines of K 39, K 40, and K 41 measured with a femtosecond laser frequency comb." Physical Review A—Atomic, Molecular, and Optical Physics 74.3 (2006): 032503.
