Notes. Columns correspond to the true (spectroscopically classified) galaxies, stars, and AGNs. Rows correspond to objects classified as galaxies, AGNs, and stars by our classifier. The values marked in bold are correctly classified objects (galaxies, AGNs, and stars) in defined i′-based apparent magnitude bins. Ratio of classified objects are given in percentage.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
