The eFEDS main catalog and supplementary catalog
X-ray sources detected in the 0.2-2.3 keV band using eSASS adopting a detection likelihood threshold of 5. The sources with detection likelihood >6 are selected as the main eFEDS catalog (27910 sources), and the less reliable ones with likelihood <6 are stored in a supplementary catalog (4774 sources).
