论文摘要
USNO Bright Star Catalog（UBSC）是1423个最亮星的新的天文镜目录，覆盖了整个天空，该星星在网上发布。除了三个恒星系统外，它几乎完整到$ v = 3 $ mag。该目录的基础是河马中级天文学数据和两个专用地面运动的河马中间的天文解决方案。每个恒星的星体参数包括位置坐标，视差，适当的运动成分及其在Hipparcos上的协方差，平均值Epoch 1991.25。 64％的目录被标记为已知或怀疑的双恒星。瑞银（UBSC）列出了Gaia EDR3中缺少68颗星，另外114颗没有Gaia视差或适当运动的星星。为了适当的动作而达到的正式精度与盖亚相当。
USNO Bright Star Catalog (UBSC) is a new astrometric catalog of 1423 brightest stars covering the entire sky, which is published online. It is nearly complete to $V=3$ mag except for three stellar systems. A combined astrometric solution of the Hipparcos Intermediate Astrometry Data and two dedicated ground-based campaigns in 2013 -- 2020 is the basis for this catalog. The astrometric parameters for each star include position coordinates, parallax, proper motion components, and their covariances on the Hipparcos mean epoch 1991.25. 64 percent of the catalog are flagged as known or suspected double or binary stars. UBSC lists 68 stars missing in Gaia EDR3 and another 114 stars without Gaia parallaxes or proper motions. The formal precision achieved for proper motions is comparable to that of Gaia.
