VizieR Online Data Catalog: KMTNet-SAAO observation of near-Earth asteroids (Erasmus+, 2017)
Abstract
Observations were made with the Sutherland, South Africa, node of the KMTNet (Kim et al. 2016JKAS...49...37K). The telescope has a primary mirror of 1.6 m in diameter and is fitted with four 9kx9k CCDs, mosaicking the 2°x2° field of view. Each CCD covers 1°x1° of sky with a plate-scale of 0.40 arcsec/pixel. The vertical and horizontal gaps between the CCDs are 184" and 373", respectively. Johnson-Cousins B-, V-, R-, and I-filters are installed and only sidereal tracking is available. The minimum recommended exposure time for an efficient cyclical observation is 60 s due to the large readout time of ~75 s. Observations were completed over 23 nights falling between 2016 October 25 and 2017 February 20, and newly discovered NEAs were specifically targeted for this study. On average, 1-2 new NEAs are discovered every night (Galache et al. 2015P&SS..111..155G) and recorded in the Minor Planet Center's (MPC) NEA database (http://minorplanetcenter.net/).
