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.
