Notes. The first column lists the catalog survey name, followed by the number of counterparts found, the band frequency or wavelength of the survey, the number of sources per square degree within the ACT fields, the radius of association used, and the probability that a given association is random.
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.
