该数据集提供了来自多个成像巡天（特别是Legacy DR10和HSC PDR3 Wide）的星系切块图像、自然语言描述、文本嵌入和图像嵌入。每一行对应一个星系，包含：预处理后的RGB星系图像、由GPT模型生成的标题、标题的摘要、由文本嵌入模型生成的文本嵌入以及AION-1-Base图像嵌入（标记的平均值）。数据集旨在支持天文学研究，特别是星系形态学和语义搜索任务。This dataset provides galaxy cutout images, natural-language descriptions, text embeddings, and image embeddings for galaxies drawn from multiple imaging surveys (specifically Legacy DR10 and HSC PDR3 Wide). Each row corresponds to a single galaxy and contains: A preprocessed RGB galaxy image, a caption generated by GPT models, a summary of the caption, text embeddings for the caption and summary produced by text-embedding models, and an AION-1-Base image embedding (mean over tokens). The dataset is designed to support astronomical research, particularly in galaxy morphology and semantic search tasks.
