The SumThreshold Method for Radio Frequency Interference …

WebAfter removing the estimated baseline, several novel strategies were proposed based on the SumThreshold algorithm for detecting different types of RFI. The threshold parameter in the SumThreshold can be determined automatically and adaptively. The adaptiveness is essential for reducing human interventions and the online RFI processing pipeline. http://zmtt.bao.ac.cn/GPPS/RFI/ bright red flannel sheet sets twin
