收藏资源简介：
这是一个天文学数据集，包含516,525个训练样本，每个样本由多维图像数据（如天体图像）和相关的天体物理参数组成。特征包括天体标识符（specObjID和bestObjID）、分类信息（class和subClass）、红移（z和zErr）、坐标（ra和dec）、光度红移（zphot）、消光值（EBV）、孔径半径（petroR90_r）以及宿主位置坐标（host_pos）。数据集大小为约43.05 GB，下载大小约为43.36 GB，主要用于天文学研究，如星系分类或天体物理分析。
This is an astronomy dataset containing 516,525 training samples, each consisting of multi-dimensional image data (e.g., celestial object images) and associated astrophysical parameters. Features include object identifiers (specObjID and bestObjID), classification information (class and subClass), redshift (z and zErr), coordinates (ra and dec), photometric redshift (zphot), extinction value (EBV), aperture radius (petroR90_r), and host position coordinates (host_pos). The dataset size is approximately 43.05 GB, with a download size of about 43.36 GB, primarily used for astronomical research such as galaxy classification or astrophysical analysis.
