Advanced LIGO 探测器的校准是对探测器对引力波的响应进行量化。入射到探测器上的引力波引起干涉仪激光的相移，该相移在探测器输出处被读出为强度波动。了解探测器对引力波的响应对于产生准确且精确的引力波应变数据至关重要。双黑洞和中子星参数的估计以及广义相对论的测试需要经过良好校准的数据，因为错误校准会导致有偏差的结果。我们描述了在第一次和第二次观测运行中为 LIGO 探测器生成校准不确定性估计的方法。
Calibration of the Advanced LIGO detectors is the quantification of the detectors’ response to gravitational waves. Gravitational waves incident on the detectors cause phase shifts in the interferometer laser light which are read out as intensity fluctuations at the detector output. Understanding this detector response to gravitational waves is crucial to producing accurate and precise gravitational wave strain data. Estimates of binary black hole and neutron star parameters and tests of general relativity require well-calibrated data, as miscalibrations will lead to biased results. We describe the method of producing calibration uncertainty estimates for both LIGO detectors in the first and second observing runs.
