本文利用模拟的LIGO和Virgo噪声数据对引力波爆发的六种搜索方法进行了比较研究。根据两个4 km LIGO干涉仪和3 km Virgo干涉仪的设计灵敏度生成模拟数据。搜索应用于数据集的复制品，其中注入了八种不同的信号。在这项分析中采用了三个品质因数：（a）接收器操作员特征曲线，（B）为达到50%和90%的效率而进行搜索所需的信噪比，以及（c）估计引力波爆发到达时间的方差和偏差。
We present a comparative study of six search methods for gravitational wave bursts using simulated LIGO and Virgo noise data. The simulated data were generated according to the design sensitivity of the two 4 km LIGO interferometers and the 3 km Virgo interferometer. The searches were applied on replicas of the data sets to which eight different signals were injected. Three figures of merit were employed in this analysis: (a) receiver operator characteristic curves, (b) necessary signal-to-noise ratios for the searches to achieve 50% and 90% efficiencies and (c) variance and bias for the estimation of the arrival time of a gravitational wave burst.
