@article{Baker2002TheLP, title={The Lazarus project : A pragmatic approach to binary black hole}, author={John G. Baker and Manuela Campanelli and Carlos O. Lousto}, journal={Physical Review D}, year={2002}, volume={65} }

We present a detailed description of techniques developed to combine 3D numerical simulations and, subsequently, a single black hole close-limit approximation. This method has made it possible to compute the first complete waveforms covering the post-orbital dynamics of a binary‐black-hole system with the numerical simulation covering the essential nonlinear interaction before the close limit becomes applicable for the late time dynamics. In order to couple full numerical and perturbative…

Because of the gauge problems, an approximated embedding method is developed which approximates location of the numerical slice into the Kerr spacetime and is much less sensitive to the gauge perturbations.
