Detailed Description

Tabulated Quasi-Normal Mode Information for Ringdown.

This file contains listed final spin values, and corresponding Quasi-Normal-Mode(QNM) central frequencies and decay rates. The spins are on [-1,1] where values are the dimensionless Kerr parameters S/M^2. The frequencies and decay rates are in units of 1/(s*pi*M), where M is 1. To compare values with tables given at, for example, www.phy.olemiss.edu/~berti/ringdown/, multiply by 2*pi, and note that the decay rate corresponds to the imaginary part of the QNM frequency.

Values for spins between -0.994 and 0.994 were sourced from the above website (2014), while qualitatively accurate values for the remaining spins where sourced from the implementation used in arxiv:1404:3197. Both references use the analytic representation of QNMs developed by Leaver in 1986, and for spin values within +-0.994, have identical values within numerical error.

◆ MAX_ALLOWED_MASS_RATIO

#define MAX_ALLOWED_MASS_RATIO 5000
