选定天区 Gaia 关联高纯度 QSO、星系和恒星候选星表，20260521-V5 版
本数据集为 QSO Selection 项目处理形成的 Gaia 源级别高纯度候选星表产品，发布版本为 20260521-V5。数据集包含三张主表：QSO 候选星表、GALAXY 候选星表和 STAR 候选星表，并提供按天区拆分的子表及 COSMOS QSO 优先级清单。星表基于 Gaia DR3 源标识、天体测量信息、光学/红外特征、多巡天光谱标记、模型评分和按 E(B-V) 分箱校准的阈值标记生成。QSO 主表主要用于选定天区内高纯度光谱后随观测目标筛选，不应解释为全天 QSO 完备星表或全天面密度测量。发布包同时包含字段说明、天区统计、文件清单、质量控制信息、数据来源记录和校验值。
