我们提出了一个银河系疏散星团中蓝离散星候选者的目录。它是基于对星系团的色星等图的检查，它更新并取代了第一个版本（Ahumada & Lapasset 1995）。对每一组进行了新的文献检索，所得信息编入两个表格。对一些方法方面进行了修订，特别是在图表中选定离散体的区域划界方面。在427个所有年龄的疏散星团中，总共发现了1887个蓝离散候选者，比原来的数量增加了一倍。编目的恒星主要根据成员信息分为两类。
We present a catalogue of blue-straggler candidates in galactic open clusters. It is based on the inspection of the colour–magnitude diagrams of the clusters, and it updates and supersedes the first version (Ahumada & Lapasset 1995). A new bibliographical search was made for each cluster, and the resulting information is organised into two tables. Some methodological aspects have been revised, in particular those concerning the delimitation of the area in the diagrams where the stragglers are selected. A total of 1887 blue-straggler candidates have been found in 427 open clusters of all ages, doubling the original number. The catalogued stars are classified into two categories mainly according to membership information.
