Computes the final mass and spin of the black hole resulting from merger.
They are given by fittings of NR simulations results. Specifically, for EOBNR, Table I of Buonanno et al. PRD76, 104049; for EOBNRv2 and EOBNRv2HM, Eqs. 29a and 29b of Pan et al. PRD84, 124052; for SEOBNRv1, SEOBNRv2, Eq. 8 of Tichy and Marronetti PRD78, 081501 and Eqs. 1 and 3 of Barausse and Rezzolla ApJ704, L40. Complemented by https://dcc.ligo.org/T1400476. For SEOBNRv4P: i) the final mass comes from Eq(3) in https://dcc.ligo.org/T1400476, but we use q<=1; ii) the final spin comes from Eq(13-16) for Hofmann et al, https://iopscience.iop.org/article/10.3847/2041-8205/825/2/L19/meta [arxiv:1605.01938]

This function generates the quasinormal mode frequencies for a black hole ringdown.
At present, this function works for the 22, 21, 33, 44 and 55 modes, and includes 8 overtones. The final frequencies are computed by interpolating the data found on the webpage of Vitor Cardoso, http://centra.ist.utl.pt/~vitor/?page=ringdown In this page, frequecy data are given for positive final spins only. For a negative final spin chi<0 case, the (l,m) mode frequency is given by the (l,-m) mode frequency of the positive final spin -chi case.
