The copies of
The Third Reference Catalogue of Bright
Galaxies, by G. de Vaucouleurs, A. de Vaucouleurs,
H.G. Corwin, R.J. Buta, G. Paturel, and P. Fouqué
A Catalogue of Rich Clusters of
Galaxies, by G.O. Abell, H.G. Corwin, and R.P. Olowin,
A Southern Galaxy Catalogue by
H.G. Corwin, A. de Vaucouleurs, and G. de Vaucouleurs,
found here are corrected versions of the published catalogues. Though
all three are available as printed and bound books, the electronic
versions are preferred for reference as all known errata occuring in
the printed versions have been corrected. Please let me know if you
find any further errors.
Brief explanations of the
data are also available electronically; the full introductions with
figures, tables, and references are only available in the printed versions.
A final version (1.4.3) of
A South-Equatorial Galaxy Catalogue by
Harold G. Corwin, Jr. and Brian A. Skiff.
is now available. This has accurate positions, diameters, position angles,
and de Vaucouleurs revised Hubble-Sandage (VRHS) types for 3333 single or
multiple galaxies in the south-equatorial declination zones between +3 degrees
and -21 degrees. The data were gleaned from POSS1 103a-O copy plates, then
checked against the UKST IIIa-J portion of the DSS. The corrected position
angles and VRHS types are published here in full for the first time. Notes on
the individual objects are also available. SEGC provides a finding list for
galaxies generally larger than about 1.8 arcmin at the 25.0 B-mag arcsec^-2 in
the south-equatorial zone.
All of these catalogues are freely accessible; I and my coauthors
ask only a reference and/or an acknowledgment if you use data from
The de Vaucouleurs Atlas of Galaxies
The de Vaucouleurs
Atlas of Galaxies by Ronald J. Buta, Harold G. Corwin, Jr., and
Stephen C. Odewahn was published in 2007 by
Press. It illustrates the classification of
galaxies in the de Vaucouleurs revised Hubble-Sandage system with over 500
calibrated digital images of nearby galaxies. It also has an extended
introduction presenting our latest understanding of how physical processes
shape galaxies and drive their evolution.
Current versions of my NGC/IC position and notes files
are available here. Check back now and then for updates.
