我们完成了由韩国微透镜望远镜网络(KMTNet)异常探测器发现的所有2018年黄金场微透镜行星的分析。在之前未发表的十个具有明确行星解的事件中，有八个事件要么是明确的行星事件，要么是非常有可能是行星事件：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。加上之前发布的4个新的异常搜索者事件和12个先前发布的(或正在准备中的)行星，这使得异常搜索者总共发现或发现了24颗2018年的黄金场行星。连同一篇关于2018年次优质行星的准备论文，这项工作为首次根据KMTNet数据中确定的行星进行行星质量比函数的统计分析奠定了基础。通过系统地将启发式分析应用于每个事件，我们确定了它们的形式主义中的小修改，这是统一所谓的近距离简并和内外简并所需的。
We complete the analysis of all 2018 prime-field microlensing planets identified by the Korea Microlensing Telescope Network (KMTNet) Anomaly Finder. Among the ten previously unpublished events with clear planetary solutions, eight are either unambiguously planetary or are very likely to be planetary in nature: OGLE-2018-BLG-1126,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, and KMT-2018-BLG-2718. Combined with the four previously published new Anomaly Finder events and 12 previously published (or in preparation) planets that were discovered by eye, this makes a total of 24 2018 prime-field planets discovered or recovered by Anomaly Finder. Together with a paper in preparation on 2018 subprime planets, this work lays the basis for the first statistical analysis of the planet mass-ratio function based on planets identified in KMTNet data. By systematically applying the heuristic analysis to each event, we identified the small modification in their formalism that is needed to unify the so-called close-wide and inner-outer degeneracies.
