J/ApJS/96/39 The Catalog of Southern Ringed Galaxies. (Buta 1995) ================================================================================ The Catalog of Southern Ringed Galaxies, Buta, R. ================================================================================ ADC_Keywords: Abstract: The Catalog of Southern Ringed Galaxies (CSRG) is a comprehensive compilation of diameters, axis ratios, relative bar position angles, and morphologies of inner and outer rings, pseudorings, and lenses in 3,692 galaxies south of declination -17 degrees. The catalog is based on visual inspection of most of the 606 fields of the SRC-J southern sky survey, with the ESO-B, ESO-R, and Palomar Sky surveys used as auxiliaries when needed for overexposed core regions. The catalog is most complete for SRC fields 1--303 (mostly south of declination -42 degrees). There are two auxiliary tables: Table 4 includes the notes for 371 entries in the main catalog, and Table 6 includes classifications for 859 additional galaxies not part of the main catalog. Detailed analysis of 5403 duplicate estimates of ring diameters and 1606 duplicate estimates of bar/ring position angles indicates that the CSRG has very good internal precision and homogeneity in these parameters. For an ``average'' ring or lens of angular diameter 0.'6 and apparent axis ratio 0.8, the internal errors are 0.'026 in angular diameter and 6.3 degrees in bar/ring position angle. Based on a comparison with two other major sources of ring diameter measurements, the external mean error in CSRG diameters is ~3.2 times the internal error at a given diameter. Comparison of the type classifications with other catalogues indicates good agreement on interpretations of features, including family and variety.
