我们推导了适用于短持续非处理激发信号的多检测器F-统计量的显式表达式。这对于与相干搜索来自探测器网络的引力波数据中的短持续非处理激发信号相关联的模板库生产是必需的。我们将该度量的性能与参数空间所有相关维度的显式重叠计算进行了比较，发现该度量准确地预测了95%以上的重叠的检测损失统计。我们还展示了忽略探测器响应函数的变化对度规的影响。
We derive explicit expressions for the multidetector F-statistic metric applied to short-duration nonprecessing inspiral signals. This is required for template bank production associated with coherent searches for short-duration nonprecessing inspiral signals in gravitational-wave data from a network of detectors. We compare the metric’s performancewith explicit overlap calculations for all relevant dimensions of parameter space and find the metric accurately predicts the loss of detection statistic above overlaps of 95%. We also show the effect that neglecting the variations of the detector response functions has on the metric.
