LIGO探测器在2003年至2004年的两次科学运行（S2和S3）中收集了大约四个月的数据。对监测仪器物理环境和整个干涉仪操作的若干环境和辅助通道进行了分析，以确定数据的质量以及是否存在非天体物理学来源的瞬变现象。这种分析使我们能够更好地了解仪器的噪声特性，并建立这些通道中的瞬态与记录引力波应变的通道之间的相关性。通过这种方式，确定了对虚假突发事件的否决。我们提出的方法，我们遵循在这个分析和结果从S2和S3否决分析的背景下，寻找引力波爆发。
The LIGO detectors collected about four months of data in 2003-2004 during two science runs, S2 and S3. Several environmental and auxiliary channels that monitor the instruments' physical environment and overall interferometric operation were analysed in order to establish the quality of the data as well as the presence of transients of non-astrophysical origin. This analysis allowed a better understanding of the noise character of the instruments and the establishment of correlations between transients in these channels and the one recording the gravitational wave strain. In this way, vetoes for spurious burst events were identified. We present the methodology we followed in this analysis and the results from the S2 and S3 veto analysis within the context of the search for gravitational wave bursts.
