摘要:

费米卫星在飞行过程中有一种特殊的运动,这使它能够很好地捕捉到伽马射线暴。这一有利特征的副作用是,GBM探测器的光变曲线受到快速和极端变化的背景的影响。在处理这些数据之前,需要将其与背景分离。通常使用的方法对费米的大多数情况是无用的,所以我们开发了一种基于卫星运动和方向的新技术。无背景光变曲线可用于进行统计调查,因此我们展示了我们的背景过滤方法的效率,该方法提供了文献中已知的统计分析。

英文摘要:

The Fermi satellite has a particular motion during its flight which enables it to catch the gamma-ray bursts mostly well. The side-effect of this favourable feature is that the lightcurves of the GBM detectors are stressed by rapidly and extremely varying background. Before this data is processed, it needs to be separated from the background. The commonly used methods were useless for most cases of Fermi, so we developed a new technique based on the motion and orientation of the satellite. The background-free lightcurve can be used to perform statistical surveys, hence we showed the efficiency of our background-filtering method presenting a statistical analysis known from the literature.
