论文摘要
电源阵列（HERA）的氢时代是南非卡鲁沙漠的射电望远镜，努力观察宇宙黎明和电离时代。完全构造后，它将由350个天线组成，并每晚产生超过60多台（TB）的数据。为了跟上相对较高的数据速率，我们为HERA开发了实时处理（RTP）系统。 RTP负责检查数据是否可接受的质量水平和标记无法使用的数据，并提供初始校准解决方案。 RTP系统由管道管理系统组成，称为HERA_OPM软件包，数据管理系统称为图书馆员。尽管该系统是在分析HERA数据的背景下开发的，但它们具有公共和开源软件，并已设计为在其他情况下进行调整和使用。
The Hydrogen Epoch of Reionization Array (HERA) is a radio telescope in the Karoo desert of South Africa endeavoring to observe Cosmic Dawn and the Epoch of Reionization. When fully constructed, it will consist of 350 antennas and generate over 60 terabytes (TB) of data each night. In order to keep pace with the relatively large rate of data, we have developed the real-time processing (RTP) system for HERA. The RTP is responsible for inspecting data for acceptable levels of quality and flagging unusable data, as well as providing an initial calibration solution. The RTP system consists of the pipeline management system, called the hera_opm package, and the data management system, called the librarian. Though the systems have been developed in the context of analyzing HERA data, they feature public and open source software, and have been designed to be adapted and used in other contexts as necessary.
