Notes. The single-band detection produces the main X-ray catalogue, together with the supplementary catalogue of faint sources that are less reliable. The point-source catalogue and extended-source catalogues are selected from the main catalogue. The three-band detection results in sources that mostly are already in the single-band detected catalogue, and they are only used to select hard sources focusing on the 2.3–5 keV band.
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.
