Notes. The first three columns indicate the date and time for which each observation was performed. The clean beam sizes and position angle (PA, the eastward angle between the north and the major axis) have been calculated from measurements of the major and minor axis FWHM, using the CASA task imfit. The noise σ for Stokes I and V has been calculated from general casaviewer statistics by defining a region away from the source in the Stokes I and V maps, for each epoch.
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.
