V2790 Ori的数据集：测光数据、极小时刻以及光变曲线O’Connell的测量值
Si-Rui Wang ; Kai Li
本数据集为"Spectroscopic and Decade-long Photometric Observations of the Contact Binary V2790 Ori: Evidence for a Brown Dwarf Companion and a Solar-like Magnetic Activity Cycle"文章中 关于V2790 Ori的测光数据、极小时刻数据及光变曲线 O’Connell 效应的测量数据。V2790 Ori的测光数据表来自本研究于 2015-2025 年利用中国三台地基望远镜获得的自主观测的多波段光变曲线数据。极小时刻数据表为445 个跨 25 年的极小时刻数据。光变曲线 O’Connell 效应的测量数据表为22 组光变曲线的 O’Connell 效应量化数据（星等差Δm、OER 比值等）。所有数据均经标准化处理，数据经多次校验，精度可靠、时间跨度长、波段覆盖完整。本数据集可支撑对V2790 Ori的轨道周期变化、磁活动周以及黑子演化等研究内容，也可为同类天体的测光观测与数据处理提供参考。
