VizieR Online Data Catalog: OGLE, KMTNet & Spitzer EWS2017-BLG-1038 light curve (Malpas+, 2022)
Abstract
OGLE-2017-BLG-1038 was first identified as a microlensing event candidate by the Optical Gravitational Lensing Experiment early warning system (OGLE), on 2017 June 3, from their ongoing survey (mostly in the I band) using the 1.3m Warsaw telescope in the Las Campanas Observatory in Chile.
The Korean Microlensing Telescope Network (KMTNet) also discovered this event as KMT-2017-BLG-0363 and observed it in the V and I bands. OGLE-2017-BLG-1038 was observed in two overlapping KMTNet search fields (BLG03 and BLG43), from each of the three KMTNet telescopes: the Cerro Tololo Inter-American Observatory (KMT-C), the South African Astronomical Observatory (KMT-S), and the Siding Springs Observatory (KMT-A). This resulted in a cadence of ~15minutes between successive observations. The end of the event was also observed by the Spitzer Space Telescope Infrared Array Camera (IRAC) instrument at an approximately 1day cadence. While both the KMTNet and OGLE observations were made as part of regular survey operations, the Spitzer observations were scheduled for this event specifically as part of a program to enable space-parallax measurements for microlensing events. This event was selected for Spitzer observations on 2017 June 13 (HJD=7918.11) and met the objective criteria on 2017 June 19 (HJD'=7923.95). (2 data files).- Publication:
