Internal Documentation

Superradiant amplification of massless waves scattering off Kerr black holes is an important phenomena in curved spacetime. Details of the process can be found in an outstanding work by Press and Teukolsky (ApJ193, 443 (1974)), but extensive tables and routines to compute them are lacking. We provide here such data. The routines are freely available, but we would appreciate if you refer to the original work.
