标题： A LOFAR RFI detection pipeline and its first results

摘要： 射电天文学正在进入一个新时代，新的和未来的射电天文台，如低频阵列（LOFAR）和平方公里阵列（Square Kilometer Array），推动了这一进程。 我们详细描述了一个自动化剔除干扰数据的流程，并对其性能进行了评估。 与相关计算成本相比，该流程仅占一小部分，同时利用了之前介绍的SumThreshold方法，被发现既快速又在高精度方面无与伦比。 借助此流程，分析了LOFAR的射电环境。 LOFAR的高时间和光谱分辨率使得观测站中由于射频干扰（RFI）而丢失的数据仅占百分之几。 显示英文摘要

摘要： Radio astronomy is entering a new era with new and future radio observatories such as the Low Frequency Array and the Square Kilometer Array. We describe in detail an automated flagging pipeline and evaluate its performance. With only a fraction of the computational cost of correlation and its use of the previously introduced SumThreshold method, it is found to be both fast and unrivalled in its high accuracy. The LOFAR radio environment is analysed with the help of this pipeline. The high time and spectral resolution of LOFAR have resulted in an observatory where only a few percent of the data is lost due to RFI.
