标题： Geometrical Expression of the Angular Resolution of a Network of Gravitational-Wave Detectors and Improved Localization Methods

摘要： 我们首次报告了一种与方法无关的几何表达式，用于任意干涉引力波（GW）探测器网络的角分辨率，当引力波到达时间未知时。 我们讨论了我们的结果对如何提高GW网络的角分辨率以及定位方法的改进的影响。 展示了一个对未知波形引力波的零流定位方法的改进示例。 显示英文摘要

摘要： We report for the first time a method-independent geometrical expression for the angular resolution of an arbitrary network of interferometric gravitational wave (GW) detectors when the arrival-time of a GW is unknown. We discuss the implications of our results on how to improve angular resolutions of a GW network and on improvements of localization methods. An example of an improvement to the null-stream localization method for GWs of unknown waveforms is demonstrated.
