Notes. The 201 examined sources were those with a continuum flux density S150 MHz > 100 mJy. In the top list of six sources, 5% are expected to be false detections (i.e. less than one). In the full table 50% of the sources are expected to be false detections. The sources are sorted by increasing p-value. The names starting with a J are the names of the sources with counterparts in NVSS. The only exception is J132941.5+471734, that does not have any NVSS counterpart; the name comes from SDSS. Note that the coordinates listed here are those of the total-intensity source, not the exact location where a polarization peak was detected.
Due to the uncertainty of the polarization calibration, the calibration error has not been included.
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.
