Galaxy Zoo DECaLS

该数据集包含了来自DESI遗产成像调查的17,736张银河图像，该调查整合了来自北京-亚利桑那天空调查（BASS）、DECam遗产调查（DECaLS）和梅奥z波段遗产调查的数据。每张图像具有1660个可见度采样点，图像尺寸设定为256×256像素。其中5000张图像被随机划分用于测试，剩余的则用于训练。规模上，这一数据集包含17,736张银河图像，其任务是进行射电干涉仪可见度重建。

This dataset contains 17,736 galaxy images from the DESI Legacy Imaging Surveys, which integrates data from the Beijing-Arizona Sky Survey (BASS), DECam Legacy Survey (DECaLS), and Mayo z-band Legacy Survey. Each image includes 1,660 visibility sampling points and has a resolution of 256 × 256 pixels. A total of 5,000 images were randomly split for the test set, while the remaining samples were used for training. The core task of this dataset, which comprises 17,736 galaxy images in total, is radio interferometer visibility reconstruction.
