摘要
我们完成了由 KMTNet AnomalyFinder 识别的所有 2018 主视场微透镜行星的分析。在 10 个此前未发表且具有明确行星解的事件中，8 个要么无歧义为行星，要么极可能为行星性质：OGLE-2018-BLG-1126、KMT-2018-BLG-2004、OGLE-2018-BLG-1647、OGLE-2018-BLG-1367、OGLE-2018-BLG-1544、OGLE-2018-BLG-0932、OGLE-2018-BLG-1212 和 KMT-2018-BLG-2718。结合此前发表的 4 个新 AnomalyFinder 事件以及 12 个由人工发现且已发表（或在准备中）的行星，这使得 AnomalyFinder 发现或回收的 2018 主视场行星总数达到 24 颗。连同一篇关于 2018 次主视场行星的在准备论文，本工作为基于 KMTNet 数据中识别的行星进行行星质量比函数的首次统计分析奠定了基础。通过对每个事件系统应用 Hwang 等人（2022）的启发式分析，我们识别出其形式化中所需的小修正，以统一所谓的近/远简并和内/外简并，正如所推测的
