VizieR Online Data Catalog: ATLAS c-o colors and classification of asteroids (Erasmus+, 2020)

Observations were performed between 2015 and 2018 by the Asteroid Terrestrial-impact Last Alert System (ATLAS). The two current ATLAS units, both located in Hawaii, are 0.5m telescopes each covering 30deg² field-of-view in a single exposure; they scan the complete visible northern sky every night. The main survey mode mostly utilizes two custom filters, a "cyan" or c-filter with a bandpass between 420 and 650nm and an "orange" or o-filter with a bandpass between 560 and 820nm.
