一个新的Stroember-Crawford紫外-β测光星表
A new catalogue of Stroemgren-Crawford uvbybeta photometry
摘要：
一个新的全天空目录的所有现有的uvbybeta测量从文献中产生。uvbybeta测光系统广泛用于研究各种银河系和河外天体。它测量由于温度差异、巴耳末不连续性和由于金属的覆盖吸收而产生的颜色。根据Tycho-2星表对各颗恒星的数据进行了交叉核对。这个星表包括非常精确的天体坐标，但星等和空间分辨率有限。然而，物体的损失只是微不足道的，并通过同质性的增益来补偿。总共使用了60668颗恒星的298639次测量结果来推导未加权平均指数及其误差。光电和CCD观测以同样的方式处理。所提供的数据集可用于各种应用，如天体物理参数的新校准、新观测的标准化，以及作为正在进行和即将进行的全天巡天的补充信息。
英文摘要：
A new all-sky catalogue of all available uvbybeta measurements from the literature was generated. The uvbybeta photometric system is widely used for the study of various Galactic and extragalactic objects. It measures the colour due to temperature differences, the Balmer discontinuity, and blanketing absorption due to metals. The data for the individual stars were cross-checked on the basis of the Tycho-2 catalogue. This catalogue includes very precise celestial coordinates, but is magnitude and spatial resolution limited. However, the loss of objects is only marginal and is compensated for by the gain of homogeneity. In total, 298 639 measurements of 60 668 stars were used to derive unweighted mean indices and their errors. Photoelectric and CCD observations were treated in the same way. The presented data set can be used for various applications such as new calibrations of astrophysical parameters, the standardization of new observations, and as additional information for ongoing and forthcoming all-sky surveys.
