Scientific paper

We present recently calculated waveforms from numerical relativity and their application to the search for and precision measurement of black hole binary coalescences. We investigate the potential contribution from the merger portion of the waveform to decreasing the uncertainties in the measurement of the binary's parameters. Until now, only the inspiral has been used for such studies due to the lack of availability of mergers and, for the case of LISA, the increased complexity required in moving beyond the low frequency approximation of the interferometer, which is necessary when mergers are included. We present preliminary results and compare to estimates for the systematic theoretical error in our waveforms, thereby verifying that we will be able to realize the level of precision from noise-induced statistical error.
