在VLA-COSMOS Deep项目的背景下，获得了COSMOS场中心度的1.4 GHz额外VLA A阵列观测结果，并与VLA-COSMOS Large项目的现有数据相结合。一个新构建的分辨率为2. ″ 5的Deep镶嵌图被用来搜索中心50 ′ × 50 ′处的1 σ <$12 μ Jy束流− 1的4 σ以下的源。这个新的星表与Large项目的星表（分辨率为1. ″ 5 × 1. ″ 4）相结合，构成了一个新的联合星表。新的联合星表中列出的所有源在1.5 ″和/或2.5 ″分辨率下的峰值通量密度都为1.5 σ，以说明这样一个事实，即在这些低通量水平下的相当大一部分源预计将在1.5 ″分辨率下略微分辨。联合目录中列出的所有属性（例如峰值通量密度、积分通量密度和源大小）都在2.”5分辨率的深度图像中确定。此外，联合目录包含43个新发现的多组分来源。
In the context of the VLA-COSMOS Deep project, additional VLA A array observations at 1.4 GHz were obtained for the central degree of the COSMOS field and combined with the existing data from the VLA-COSMOS Large project. A newly constructed Deep mosaic with a resolution of 2.″5 was used to search for sources down to 4σ with 1σ ≈ 12 μJy beam−1 in the central 50′ × 50′. This new catalog is combined with the catalog from the Large project (obtained at 1.″5 × 1.″4 resolution) to construct a new Joint catalog. All sources listed in the new Joint catalog have peak flux densities of ⩾5σ at 1.″5 and/or 2.″5 resolution to account for the fact that a significant fraction of sources at these low flux levels are expected to be slightly resolved at 1.″5 resolution. All properties listed in the Joint catalog, such as peak flux density, integrated flux density, and source size, are determined in the 2.″5 resolution Deep image. In addition, the Joint catalog contains 43 newly identified multi-component sources.
