This approach is based on the Buonanno, Kidder, and Lehner method for binary black holes, and it is successfully tested against the results of numerical-relativity simulations: the dimensionless spin parameter is predicted with absolute error $\\lesssim 0.02$, whereas the relative error on the final mass is $\\lesssim 2$%, its distribution in the tests being pronouncedly peaked at $1$%.
