在射电天文领域,SKA项目以及作为 SKA早期项目如 MeerKAT,APERTIF,ASKAP 和中国的 FAST的提出与建设很快就会将射电天文学带入一个海量数据产生的新时代。这些海量的数据需要研究者搜集、管理、处理分析和存储,计算机控制下自动分类筛选预处理迫在眉睫。寻找有效的方法在巡天收集的大量数据中来确定独特的源的模拟工作正在进行。针对 GASKAP (ASKAP 银道面谱线巡天项目)目前用到的源查找工具主要有 Duchamp、Clumpfind、Seleavy等。我们比较几种工具找源的表现,以提高目标源查找的效率。

The SKA proj ect and SKA peer proj ects such as MeerKAT,APERTIF,ASKAP and the FAST will lead radio astronomy into a new era of vast amounts of data.The vast amounts of data requires researchers to collect,manage,analyze and store,so computer-controlled automatic classification filter pretreatment is imminent.We are making progress on simulation of large amounts of data to select candidate sources.The source finding tools used include Duchamp,Clumpfind,Seleavy.We compare the performances of several tools in order to improve efficiency of source finding.
