Notes. The integrated flux densities were obtained by summing all pixels above 3σ. The PSF given is the restoring beam as calculated and used by the CLEAN algorithm. Uncertainties on peak brightness include both calibration and image noise as .
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.
