论文摘要
在分析引力波检测器（例如Ligo）的数据时，散射光的过量噪声构成了持续的挑战。我们将这些“小故障”行为的有力动机模型整合到了重力波科学中使用的标准贝叶斯分析管道中。这允许在此模型中推断自由参数，并将这些模型的减法删除以产生数据的无故障版本。我们表明，即使这些特征在数据的标准可视化中可能无法识别，这种推断是对这些故障特征的存在的有效歧视者。
Excess noise from scattered light poses a persistent challenge in the analysis of data from gravitational wave detectors such as LIGO. We integrate a physically motivated model for the behavior of these "glitches" into a standard Bayesian analysis pipeline used in gravitational wave science. This allows for the inference of the free parameters in this model, and subtraction of these models to produce glitch-free versions of the data. We show that this inference is an effective discriminator of the presence of the features of these glitches, even when those features may not be discernible in standard visualizations of the data.
