Distribution of SB at 144 MHz of the core-D AGNs sample (black), and the final sample of 69 candidate restarted galaxies (red) as discussed in Sect. 3.5. We note that the six candidate restarted galaxies selected only by SSC criteria presented in Sect. 3.2 are indicated in blue color. The mean and median values of SB of candidate restarted galaxies are 14.6 and 10.5 mJy arcmin⁻² respectively.
