标题： Three editions of the Star Catalogue of Tycho Brahe

摘要： 第谷·布拉赫于1598年完成了他的星表，其中包含了1004颗固定星的位置和亮度。 该星表以手稿形式流传。 布拉赫编辑了一个较短版本的星表，包含777颗恒星，并于1602年印刷出版；开普勒则编辑了完整的包含1004颗恒星的星表，并于1627年印刷出版。 我们提供了这三个版本星表的机器可读版本，描述了它们之间的差异，并基于与赫比斯星表现代数据的比较，简要讨论了它们的准确性。 我们也比较了我们的结果与Dreyer（1916）和Rawlins（1993）的早期分析，发现总体上一致。 布拉赫给出的亮度值与现代值相关性很好，他的黄经和黄纬误差分布宽度约为2角分，具有比高斯分布更多的大误差星星（尤其是最暗淡的星星）。 超过10角分位置误差的条目约占总数的15%，这些错误可能是计算或抄写错误造成的。 显示英文摘要

摘要： Tycho Brahe completed his catalogue with the positions and magnitudes of 1004 fixed stars in 1598. This catalogue circulated in manuscript form. Brahe edited a shorter version with 777 stars, printed in 1602, and Kepler edited the full catalogue of 1004 stars, printed in 1627. We provide machine-readable versions of the three versions of the catalogue, describe the differences between them and briefly discuss their accuracy on the basis of comparison with modern data from the Hipparcos Catalogue. We also compare our results with earlier analyses by Dreyer (1916) and Rawlins (1993), finding good overall agreement. The magnitudes given by Brahe correlate well with modern values, his longitudes and latitudes have error distributions with widths of about 2 arcmin, with excess numbers of stars with larger errors (as compared to Gaussian distributions), in particular for the faintest stars. Errors in positions larger than 10 arcmin, which comprise about 15 per cent of the entries, are likely due to computing or copying errors.
