我们描述了从LIGO和Virgo数据中寻找引力波的实施。这种全天、全天、多探测器的双星聚结搜索已被用于搜索最近LIGO和Virgo运行中获取的数据。搜索是围绕数据的匹配滤波器分析建立的，并通过许多信号一致性测试进行增强，这些测试旨在区分非高斯检测器噪声的伪影和潜在检测。我们使用高斯噪声和来自第五次LIGO科学运行的数据展示了搜索性能，并证明信号一致性测试能够减轻非高斯噪声的影响，并提供与高斯噪声相当的灵敏度。
We describe the implementation of a search for gravitational waves from compact binary coalescences in LIGO and Virgo data. This all-sky, all-time, multidetector search for binary coalescence has been used to search data taken in recent LIGO and Virgo runs. The search is built around a matched filter analysis of the data, augmented by numerous signal consistency tests designed to distinguish artifacts of non-Gaussian detector noise from potential detections. We demonstrate the search performance using Gaussian noise and data from the fifth LIGO science run and demonstrate that the signal consistency tests are capable of mitigating the effect of non-Gaussian noise and providing a sensitivity comparable to that achieved in Gaussian noise.
