Age-metallicity relation of {omega} Cen

We present a metallicity distribution based on photometry and spectra for 442 Omega Centauri cluster members that lie at the main-sequence turnoff region of the color-magnitude...我们基于测光（photometry）与光谱（spectra）数据，为442颗位于颜色-星等图主序星转离点区域的半人马座ω（Omega Centauri）星团成员构建了金属丰度分布。
