Allen Telescope Array Twenty-centimeter Survey (ATATS)

ATATS数据集是由加州大学伯克利分校创建，旨在通过多时期、约700平方度的1.4 GHz射电图像和目录，探测罕见、明亮的瞬态现象，并验证ATA的大视场调查能力。该数据集覆盖广泛，包含4984个源，用于研究多时期瞬态和变源调查中的动态范围限制和变化（u, v）覆盖。数据集的创建过程涉及使用新版本的RAPID软件进行数据处理，以提高图像质量。ATATS数据集主要应用于射电天文学领域，特别是在瞬态天体物理学的研究中，旨在解决瞬态现象的探测和分析问题。

The ATATS dataset was developed by the University of California, Berkeley. It is designed to detect rare and bright transient astronomical phenomena and validate the large-field survey capabilities of the ATA through multi-epoch 1.4 GHz radio images and catalogs spanning approximately 700 square degrees. This comprehensive dataset includes 4984 sources, and is utilized to investigate dynamic range limitations and (u, v) coverage variations in multi-epoch transient and variable source surveys. The creation of the dataset employed an updated version of the RAPID software for data processing to enhance image quality. Primarily deployed in the field of radio astronomy, especially for transient astrophysics research, the ATATS dataset aims to resolve challenges associated with the detection and analysis of transient phenomena.
