Hevelius星表

The Star Catalogue of Hevelius

Frank Verbunt, Robert H. van Gent

摘要:

约翰内斯·赫维留的目录包含了1564个条目的位置和星等,由他的妻子伊丽莎白·库普曼于1690年出版。我们提供了一个机器可读版本的目录,并简要讨论其准确性的基础上,与现代依巴谷星表的数据进行比较。我们将我们的结果与Rybka(1984)的早期分析进行了比较,发现总体一致。赫维留给出的数量与现代价值观有很好的相关性。他的位置测量的准确性与Brahe的相似,其中sigma=2 arcmin,比高斯分布的预期误差更大。位置精度随震级的增加而缓慢下降。位置误差大于一度的恒星比例为1.5%,比布拉赫星表中的5%比例要小。

英文摘要:

The catalogue by Johannes Hevelius with the positions and magnitudes of 1564 entries was published by his wife Elisabeth Koopman in 1690. We provide a machine-readable version of the catalogue, and briefly discuss its accuracy on the basis of comparison with data from the modern Hipparcos Catalogue. We compare our results with an earlier analysis by Rybka (1984), finding good overall agreement. The magnitudes given by Hevelius correlate well with modern values. The accuracy of his position measurements is similar to that of Brahe, with sigma=2 arcmin for with more errors larger than 5 arcmin than expected for a Gaussian distribution. The position accuracy decreases slowly with magnitude. The fraction of stars with position errors larger than a degree is 1.5 per cent, rather smaller than the fraction of 5 per cent in the star catalogue of Brahe.
