描述了 VLA-COSMOS 大型项目并讨论了其科学目标。我们提供了在 1.4 GHz 2 deg2 COSMOS 场中发现的约 3600 个无线电源的目录。 VLA A 和 C 配置中的观测结果导致分辨率为 1.5″ × 1.4″，中心 1 (2) deg2 的平均均方根噪声约为 10.5 (15) μJy beam-1。八十个射电源明显扩展，由多个组件组成，其中大多数似乎是双瓣射电星系。星表的天体测量已经过彻底测试，相对和绝对天体测量的不确定度分别为 130 mas 和 <55 mas。
The VLA-COSMOS Large Project is described and its scientific objective is discussed. We present a catalog of ~3600 radio sources found in the 2 deg2 COSMOS field at 1.4 GHz. The observations in the VLA A and C configuration resulted in a resolution of 1.5′′ × 1.4′′ and a mean rms noise of ~10.5 (15) μJy beam-1 in the central 1 (2) deg2. Eighty radio sources are clearly extended consisting of multiple components, and most of them appear to be double-lobed radio galaxies. The astrometry of the catalog has been thoroughly tested, and the uncertainty in the relative and absolute astrometry are 130 and <55 mas, respectively.
