Recent years have seen tremendous progress in numerical relativity and an ever improving performance of ground-based interferometric gravitational wave detectors. The numerical relativity and gravitational wave data analysis communities are joining forces to establish the most effective role for NR waveforms in the detection and characterization of binary black hole coalescences.
We present the status of a study of detection systematics for binary black hole coalescences. Waveforms produced with the MayaKranc code are added to colored, gaussian noise, simulated to reproduce that of ground-based interferometric detectors, and analyzed with the unmodeled burst search algorithm Omega, which is used in LIGO-Virgo burst searches. Detection efficiency and parameter accuracy are systematically weighted against morphological parameters such as black hole spins and masses, orbit eccentricity, and mass ratio, as well as numerical details such as waveform accuracy and duration, the number of included spherical harmonic modes, and extraction radius.
