Description

Kerr quasinormal mode frequencies and excitation factors for gravitational waves (s=-2).  Normalization is 2M=1 except for the spin parameter a/M.  Data format is:

a/M, Re(2M\omega), Im(2M\omega), Re(A), Im(A), Re(\nu), Im(\nu), Re(B), Im(B)

M: mass
a: spin parameter
\omega: quasinormal mode frequency
A: separation constant
\nu: renormalized angular momentum
B: excitation factor
