Cumulative distribution of sources per energy flux detected at a characteristic radio frequency of 1.28 GHz. The two histograms correspond to the two assumptions for an upper or lower limit of qBHXBs populating a Lorimer-like distribution in the disc. We show for comparison the detection threshold of radio sources with current facilities, such as MeerKAT and VLA (∼10 μJy).
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.
