The HLA Star Cluster Project ("HLASTARCLUSTERS")

Compact star cluster catalogs are presented for 20 nearby, star-forming galaxies using observations from the Advanced Catalog for Surveys (ACS) and source lists generated by the Hubble Legacy Archive. A typical cluster luminosity function can be approximated by a power-law, with an average value for the index of -2.37 and rms scatter = 0.18. The uniform database provided by these HLA catalogs results in a small scatter (0.5 magnitude) in the correlation between the magnitude of the brightest cluster (M_brightest) and log of the number of clusters brighter than M_I = -9 (log N).

利用先进巡天目录（Advanced Catalog for Surveys，ACS）的观测数据以及哈勃遗产档案（Hubble Legacy Archive，HLA）生成的源列表，本文呈现了20个邻近恒星形成星系的致密星团目录。典型的星团光度函数可由幂律近似，其指数平均值为-2.37，均方根散射（rms scatter）为0.18。这些HLA目录提供的统一数据库使得最亮星团的星等（M_brightest）与亮于M_I=-9的星团数量的对数（log N）之间的相关性具有较小的散射（0.5星等）。
