Notes. We include their multiwavelength counterparts within one LOFAR FWHM (20″). Detection (non-detection) is referred to with Y (N). (a) Names are taken from P21. (b) Types are taken from P21. The label “‡” indicates sources present in the NASA/IPAC Extra-galactic Database (NED, Chen et al. 2022). (*) next to types indicate that the sources are absent in the SIMBAD-CDS astronomical database through the Aladin sky viewer (Boch & Fernique 2014). (c) Indices are used internally in this paper. (d) LOFAR emission (Radio-L) with significantly positive values (Y) at the center of each cutout map. (e) Optical emission from Pan–STARRS1 (Magnier et al. 2020). (f) Near-infrared (NIR) emission from 2MASS (Skrutskie et al. 2006) or Spitzer (Dunham et al. 2008; Evans et al. 2009). (g) Radio emission at high frequency (Radio-H) from VLA (Condon et al. 1998; Tobin et al. 2016).
