LIGO Document G0900430-v2
- Gravitational wave ground-based detectors and numerical-source codes are individually performing at a top-notch level. We explore the added benefit to the detection and understanding of gravitational wave sources made possible by joining the expertise of numericists and analysists in 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 a study of
detection systematics using waveforms produced by the MayaKranc code that are added to colored, gaussian noise and analyzed with the unmodeled burst search algorithm Omega (also 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. These detection systematics are mapped to numerical and physical choices in NR to determine the effectivess of numerical waveforms in burst analysis.
