VizieR Online Data Catalog: Multiband photometry of microlensing event Kojima-1 (Zang+, 2020)
Abstract
We use ground-based follow-up data to derive basic single-lens parameters and constrain microlens parallax. To minimize the impact on microlens parallax measurements from possible systematic errors, we choose the ground-based data that were carefully selected and used by Dong+, 2019ApJ...871...70D, including the data from All-Sky Automatic Survey for Supernovae (ASAS-SN), 0.6m telescopes at Post Observatory (RP), 0.5m Iowa Robotic Telescope (Iowa) at the Winer Observatory (Arizona, USA), 0.4m telescope at Auckland Observatory (AO), and the 1.3m SMARTS telescope at Cerro Tololo Inter-American Observatory (CTIO). For Spitzer, observations start on 2017 December 19 (HJD'=8107.2, HJD'=HJD-2450000). The observations ended on 2018 January 23 (HJD'=8143.7). In total, 21 data points were taken, all using the 3.6μm channel (L-band) of the IRAC camera.
