These sources were followed-up with MeerKAT to assess their radio morphology and enable host-galaxy identification, as existing radio images of 25 to 45-arcsec resolution do not provide sufficient information. We refer to these sources as the MeerKAT-2019 subset. The aim is to identify the host galaxy of these sources by visually inspecting the overlays comprising radio data from four surveys (at 150, 200, 843/1400, and 1300 MHz). Our morphological classification and host- galaxy identification relies upon the ~7-arcsec resolution images from MeerKAT (1300 MHz). Through the visual inspection of the overlays, 14 radio sources in the MeerKAT-2019 subset have wide-angle tail morphology, 10 are head-tail, and 5 have X-, S-/Z-shaped morphology. Most of the remaining sources have the radio morphology of typical symmetric lobes. Of 140 sources, we find host galaxies for 98 sources, leaving 42 with no identified host galaxy. These 42 sources still have ambiguous identification even with higher resolution images from MeerKAT.2023MNRAS.518.4290Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/518/4290CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/347 : KiDS-ESO-DR3 multi-band source catalog (de Jong+, 2017)II/349 : The Pan-STARRS release 1 (PS1) Survey - DR1 (Chambers+,2016)J/A+A/598/A78 : The GMRT 150MHz all-sky radio survey (Intema+, 2017)J/A+A/544/A18 : Radio galaxies of the local universe (van Velzen+, 2012)J/MNRAS/421/1569 : Properties of 18286 SDSS radio galaxies (Best+, 2012)J/MNRAS/204/151 : Bright radio sources at 178 MHz (3CRR) (Laing+ 1983)J/ApJS/199/26 : The 2MASS Redshift Survey (2MRS) (Huchra+, 2012)J/A+AS/132/31 : Kinematical models for double radio sources (Nilsson, 1998)J/AJ/131/114 : The Molonglo Southern 4Jy sample.
