cds-question@unistra.frexoplanetsphotometryvisible-astronomygravitational-lensingTo conduct a comprehensive demographic study of microlensing planets, it is essential to detect all planetary signals that exceed a predefined threshold through a detailed analysis of survey data. We reanalyzed previous data from the Korea Microlensing Telescope Network survey to search for weak planetary signals in lensing events involving faint source stars. For events with potential short-term anomalies identified in the initial search, we validated the signals using rereduced data and conducted detailed modeling of the anomalous events. This process led to the discovery of four planetary events: KMT-2017-BLG-2197, KMT-2022-BLG-1790, KMT-2022-BLG-2076, and KMT-2023-BLG-2209. For all these events, the modeling resulted in two solutions due to the well-known inner-outer degeneracy. The estimated masses of the planets and their hosts are approximately (M_p_/M_J_,M_h_/M_{sun}_)~(0.36,7.9) for KMT-2017-BLG-2197L, ~(0.6,1.7) for KMT-2022-BLG-1790L, ~(0.67,0.9) for KMT-2022-BLG-2076L, and ~(0.73,0.8) for KMT-2023-BLG-2209L. The planetary systems KMT-2017-BLG-2197L and KMT-2022-BLG-1790L are likely located in the Galactic bulge, while KMT-2022-BLG-2076L and KMT-2023-BLG-2209L are more likely situated in the disk.2025AJ....169..288Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/169/288CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/549/A147 : Abund. of microlensed bulge dwarf stars.
