论文摘要
高级处女座端长凳是从2019年4月1日至2020年3月27日的第三次观察跑步期间的散射光噪声的重要来源。我们描述了如何在在线应变数据重建过程中使用辅助通道减去该噪声。我们详细建模了散射的光噪声耦合，并证明可以实现进一步的噪声减法。我们还表明，拟合的模型参数可用于光学表征干涉仪，特别是提供了一种新的方法来确定检测器应变数据的绝对校准。
Advanced Virgo end benches were a significant source of scattered light noise during the third observing run that lasted from April 1 2019 until March 27 2020. We describe how that noise could be subtracted using auxiliary channels during the online strain data reconstruction. We model in detail the scattered light noise coupling and demonstrate that further noise subtraction can be achieved. We also show that the fitted model parameters can be used to optically characterized the interferometer and in particular provide a novel way of establishing an absolute calibration of the detector strain data.
