论文摘要
我们通过使用556星的可靠数据来得出Galex和UBV颜色之间的转换方程。我们提出两组方程式；作为（仅）亮度类别的函数，也是亮度类别和金属性的函数。金属度是从文献中提供的，而光度类别是通过本研究中使用PARSEC质量轨迹来确定的。小色残差和高方形相关系数有望准确的衍生颜色。具有可靠数据的转换方程在70颗恒星中的应用表明，金属性在估计更准确的颜色中起着重要作用。
We derive transformation equations between GALEX and UBV colours by using the reliable data of 556 stars. We present two sets of equations; as a function of (only) luminosity class, and as a function of both luminosity class and metallicity. The metallicities are provided from the literature, while the luminosity classes are determined by using the PARSEC mass tracks in this study. Small colour residuals and high squared correlation coefficients promise accurate derived colours. The application of the transformation equations to 70 stars with reliable data shows that the metallicity plays an important role in estimation of more accurate colours.
