A catalog of W UMa type eclipsing binary systems with tertiary components based on eclipse timing diagrams is presented listing the physical and orbital parameters (including third body parameters) of 150 W UMa type eclipsing binaries.

In this study, the (O–C) diagrams of nine sample W UMa type eclipsing binary systems, based on the most reliable timings of minima in the literature, are analyzed to obtain the third-body parameters and significant statistical results are presented from the data in the catalog.

基于日食时间变化的具有附加组件的 W UMa 型双星系统目录

介绍了基于日食时序图的具有三次分量的 W UMa 型食双星系统目录，其中列出了 150 W UMa 型食双星的物理和轨道参数（包括第三体参数）。

在这项研究中，基于文献中最可靠的极小值时间，分析了九个样本 W UMa 型食双星系统的（O-C）图，以获得第三体参数，并从目录中的数据。
