Notes. Listed are the ID, the position in RA and Dec, the radio flux density at 1.4 GHz, the IR flux density at 3.6 μm, the radio-to-IR flux density ratio between 1.4 GHz and 3.6 μm, the optical R band (Vega) magnitude, the on-source time, and the redshift determined in this work. Positions, flux densities, and magnitudes were taken from Norris et al. (2006).
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.
