Notes. Points at 148 MHz derive from TGSS. If not designated differently, the higher frequency points come from Bîrzan et al. (2008).
The frequencies in MHz used for power-law fitting of the radio spectra. The numbers in parentheses are the references for the literature values and have the same meaning as in Table 2.
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.
