Notes. ⁽¹⁾ Intema et al. (2017), Coppejans et al. (2017). ⁽²⁾Becker et al. (1995), White et al. (1997). ⁽³⁾Due to the low resolution ofNVSS (45″), the reported flux density of 2.5 ± 0.5 in Condon et al. (1998) is contaminated by a source located 10″ to the southof SDSSJ08. We subtracted the contribution of the contaminated source (0.44 mJy; Petric et al. 2003) from the reported value.
