Classified Chandra Sources in Globular Clusters

本数据集名为‘Classified Chandra Sources in Globular Clusters’，由乔治华盛顿大学物理系创建，专注于通过Chandra X射线天文台观测到的球状星团中的已分类X射线源。数据集包含268个已分类源，涵盖活动双星、激变变星、毫秒脉冲星和低质量X射线双星等类别。创建过程中，研究团队通过多波段观测数据与Chandra源目录（CSC）和HST紫外球状星团调查（HUGS）进行交叉匹配，提取了这些源的多波段特性。数据集主要用于机器学习分类未识别的X射线源，有助于理解恒星和双星演化及星团动力学。

This dataset, named *Classified Chandra Sources in Globular Clusters*, was created by the Department of Physics at George Washington University. It focuses on classified X-ray sources in globular clusters observed by the Chandra X-ray Observatory. The dataset contains 268 classified sources, covering categories such as active binaries, cataclysmic variables, millisecond pulsars, and low-mass X-ray binaries. During the creation process, the research team performed cross-matching between multi-wavelength observation data, the Chandra Source Catalog (CSC), and the HST Ultraviolet Globular Cluster Survey (HUGS) to extract the multi-wavelength properties of these sources. This dataset is primarily used for machine learning-based classification of unidentified X-ray sources, and helps advance the understanding of stellar and binary evolution as well as globular cluster dynamics.
