收藏资源简介：
该数据集是一个天文学数据集，包含天文观测对象的图像数据和相关物理属性。特征包括多维图像（可能为光谱或空间图像）、对象ID（specObjID和bestObjID）、分类（class和subClass）、红移（z和zErr）、天球坐标（ra和dec）、光度红移（zphot）、消光值（EBV）、半径参数（petroR90_r）以及宿主位置坐标（host_pos）。数据集主要用于天体分类、红移分析或天文对象研究，训练集包含516,525个样本，总大小约16.5GB。
This dataset is an astronomical dataset containing image data of astronomical observation objects and their associated physical properties. Its features include multi-dimensional images (which may be spectral or spatial images), object IDs (specObjID and bestObjID), classifications (class and subClass), redshifts (z and zErr), celestial coordinates (ra and dec), photometric redshifts (zphot), extinction values (EBV), radius parameters (petroR90_r), and host position coordinates (host_pos). This dataset is primarily used for celestial object classification, redshift analysis, or astronomical object research. The training set includes 516,525 samples, with a total size of approximately 16.5 GB.
