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
3692 galaxies south of declination -17°. The purpose of the
catalog is to evaluate the idea that these ring phenomena are related
to orbital resonances with a bar or oval in galaxy potentials. The
catalog is based on visual inspection of most of the 606 fields of the
Science Research Council (SRC) IIIa-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°). In addition to
ringed galaxies, a list of 859 mostly nonringed galaxies intended for
comparison with other catalogs is provided.
