Abstract:
This paper is the third which examines galaxy morphology from the
point of view of comprehensive de Vaucouleurs revised Hubble-Sandage
(CVRHS) classification, a variation on the original de Vaucouleurs
classification volume that accounts for finer details of galactic
structure, including lenses, nuclear structures, embedded disks, boxy
and disky components, and other features. The classification is
applied to the EFIGI sample, a well-defined set of nearby galaxies
which were previously examined by Baillard et al. (2011, Cat.
J/A+A/532/A74) and de Lapparent et al. (2011A&A...532A..75D 2011A&A...532A..75D). The
survey is focussed on statistics of features, and brings attention to
exceptional examples of some morphologies, such as skewed bars, blue
bar ansae, bar-outer pseudoring misalignment, extremely elongated
inner SB rings, outer rings and lenses, and other features that are
likely relevant to galactic secular evolution and internal dynamics.
The possibility of using these classifications as a training set for
automated classification algorithms is also discussed.
Description:
The catalogue provides comprehensive de Vaucouleurs revised
Hubble-Sandage (CVRHS) morphological types for the 4458 galaxies in
the EFIGI sample (A. Baillard et al., 2011, Cat. J/A+A/532/A74). For
each galaxy, the catalogue gives the name from the NASA/IPAC
Extragalactic Database (NED) or a Sloan Digital Sky Survey (SDSS)
positional name; the number in the Principal Galaxy Catalogue (PGC, G.
Paturel et al., 1989A&AS...80..299P 1989A&AS...80..299P, Cat. VII/119); the radial
velocity if known; the mean stage on the RC3 numerical scale; the mean
family (barred versus nonbarred) on a numerical scale; the number of
classifications the means are based on; and the full mean CVRHS type.
