cds-question@unistra.frsurveysradio-sourcesgalaxy-classification-systemsThe morphology of selected groups of sources in the Faint Images of the Radio Sky at Twenty Centimeters (FIRST) survey and catalog is examined. Sources in the FIRST catalog (2003 April release, 811117 entries) were sorted into singles, doubles, triples, and groups of higher-count membership based on a proximity criteria. The 7106 groups with four or more components were examined individually for bent types including, but not limited to, wide-angle tail and narrow-angle tail types. In the process of this examination, ring, double-double, X-shaped, hybrid morphology, giant radio sources, and the herein described W-shaped and tri-axial morphology systems were also identified. For the convenience of the reader separate tables for distinctive types were generated. A few curiosities were found. For the 16950 three-component groups and 74788 two-component groups, catalogs with probability estimates for bent classification, as determined by pattern recognition techniques, are presented.2011ApJS..194...31Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/194/31CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/71 : The FIRST Survey
