We visually examined 5336 image fields and found 264 tailed radio galaxies. Tailed radio galaxies are classified as wide-angle tailed (WAT) galaxies or narrow-angle tailed (NAT) galaxies, based on the angle between the two jets of the galaxy. Our sample of tailed radio galaxies included 203 WAT- and 61 NAT-type sources. These newly identified tailed sources are significant additions to the list of known tailed radio galaxies. The source morphology and luminosity features of the various galaxies and their optical identifications are presented. Other radio properties and general features of the sources are also discussed.2022MNRAS.516..372Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/516/372CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/406/2578 : Galaxies near S1189 (Mao+, 2010)J/MNRAS/463/2997 : Lockman Hole low-frequency radio sources (Mahony+, 2016)J/ApJS/194/31 : Morphology for groups in the FIRST database (Proctor, 2011)J/ApJS/199/34 : Clusters of galaxies in SDSS-III (Wen+, 2012)J/ApJS/259/31 : Head-tail radio galaxies from the VLA FIRST surveyJ/ApJS/167/1 : Galaxy groups and clusters from SDSS (Berlind+, 2006)J/ApJ/807/178 : Newly rich galaxy clusters identified in SDSS-DR12J/ApJS/224/18 : Identify giant radio sources from the NVSS (Proctor, 2016)J/AJ/148/75 : Bent-tailed radio galaxies Chandra Deep Field SouthJ/AJ/154/169 : GMRT observations of head-tail radio galaxiesJ/AJ/141/88 : Galaxy cluster environments of radio sources (Wing+, 2011)J/A+A/626/A8 : WATCAT.
