资源简介:
Recently, the first installment of data from ESA’s Gaia astrometric satellite mission (Gaia DR1) was released, containing positions of more than 1 billion stars with unprecedented precision, as well as proper motions and parallaxes, however only for a subset of 2 million objects. The second release will include those quantities for most objects.

近日,欧洲空间局(European Space Agency, ESA)盖亚天体测量卫星任务的首批数据(Gaia DR1)正式发布。该数据集包含超过10亿颗恒星的位置信息,测量精度达到前所未有的水平;同时还包含200万个子样本天体的自行与视差参数,但该类参数仅适用于该子样本。后续的第二次数据发布将覆盖绝大多数天体的上述全部参数。
