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.

is continued after column 16 in the exact same format; the data for the R1
part are in bytes 46-64; the R1R2' classification is split across the
