VizieR Online Data Catalog: Photometry of OGLE-2019-BLG-0304 with OGLE & KMTNet (Han+, 2021)

The lensing event was first found by the Early Warning System of the Optical Gravitational Microlensing Experiment (OGLE) survey on 2019 March 16. The OGLE survey utilized the 1.3m telescope located at the Las Campanas Observatory in Chile and the telescope is equipped with a camera yielding a 1.4deg² field of view. The event was rediscovered by the Korea Microlensing Telescope Network survey in its post-season analysis, and it was dubbed KMT-2019-BLG-2583. The KMTNet survey employed three identical 1.6m telescopes located at the Siding Spring Observatory (KMTA) in Australia, the Cerro Tololo Inter-American Observatory (KMTC) in South America, and the South African Astronomical Observatory (KMTS) in Africa. The camera mounted on each KMTNet telescope yields a 4deg² field of view.
