Notes. Column 1 gives the minimum flux density in mJy, Col. 2 gives the mean flux density in mJy. In Col. 3 the observed number of sources is stated. Column 4 gives the differential source density (n) in units of sr-1 Jy-1. Normalised differential counts and their Poisson errors are given in Col. 5. The number of sources in deg-2 with Poisson error is given in Col. 6.
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.
