Left: NVSS image at 1.4 GHz of the field of PBC J2333.9-2343. Contours are traced at (− 1,1,2,4,8,16,32) × 1.7 mJy beam^-1. The peak intensity is located at the core position and it is 747 mJy beam^-1. The restoring beam is circular with a 45 arcsec FWHM. Right: spectra of the north lobe (blue squares), core (red circles), and south lobe (green triangles). Additionally to NVSS data, we included the data up to 200 MHz from GLEAM (Hurley-Walker et al. 2017); at 352 MHz from WISH (De Breuck et al. 2002); the one at 5 GHz from the PMN survey (Griffith et al. 1994). For the core, we added data from The Australia Telescope 20 GHz (AT20G) Survey (Murphy et al. 2010).
