Title: Systematics of NR waveform accuracy and burst searches for binary black hole mergers Sebastian Fischetti, Laura Cadonati, Shourov Chatterji, Frank Herrmann, Satya Mohapatra, Deirdre Shoemaker 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 and addressing the question of what is 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 in the mass range where merger and ringdown constitute most of the in-band signal for ground based interferometers. Waveforms produced with the MayaKranc code are added to colored, gaussian noise and analyzed with the unmodeled burst search algorithm Qpipeline/Omega, which is used in LIGO-Virgo burst searches. Detection efficiency and parameter accuracy are systematically weighted against parameters such as spin and mass ratio as well as numerical details such as waveform accuracy, the number of included modes and extraction radius.
