分析了Virgo干涉仪在O3科学运行的第二部分（称为O3b）期间获得的数据，目的是描述与探测器周围环境中微震噪声的可变性有关的散射光噪声的开始和时间演变。所用的自适应算法，称为pytvfemd，是适合于分析的时间序列，这是非线性和非平稳。它允许在受散射光噪声影响的日子期间获得检测器的差动臂运动自由度的第一振荡模式。模式的包络线，即其瞬时振幅，然后与伦敦西区长凳，一个已知的散射光在O3的源的运动。伦敦西区测试质量和伦敦西区光具座之间的相对速度被用作散射光噪声的预测因子。在微震频带中的较高地震噪声的周期中获得较高的相关值。这也得到了GravitySpy在2020年1月至3月期间散射光故障的信噪比（SNR）的证实。所得结果表明，所采用的方法是适合散射光噪声的特性和监测引力波干涉仪。
Data acquired by the Virgo interferometer during the second part of the O3 scientific run, referred to as O3b, were analysed with the aim of characterising the onset and time evolution of scattered light noise in connection with the variability of microseismic noise in the environment surrounding the detector. The adaptive algorithm used, called pytvfemd, is suitable for the analysis of time series which are both nonlinear and nonstationary. It allowed to obtain the first oscillatory mode of the differential arm motion degree of freedom of the detector during days affected by scattered light noise. The mode’s envelope i.e. its instantaneous amplitude, is then correlated with the motion of the West end bench, a known source of scattered light during O3. The relative velocity between the West end test mass and the West end optical bench is used as a predictor of scattered light noise. Higher values of correlation are obtained in periods of higher seismic noise in the microseismic frequency band. This is also confirmed by the signal-to-noise ratio (SNR) of scattered light glitches from GravitySpy for the January–March 2020 period. Obtained results suggest that the adopted methodology is suited for scattered light noise characterisation and monitoring in gravitational wave interferometers.
