Description (Introduction of Catalog):
This compendium is a companion to the Nearby Galaxies Atlas (ref. 29;
hereafter NBG Atlas). Data has been accumulated on 2367 galaxies with
systemic velocities less than 3000 kilometers/second. Any galaxy was
admitted to the catalog if it had a known velocity in 1978 that
satisfied the specified limit of 3000 kilometers/second, or if it was
subsequently observed to have a suitable velocity in surveys of the
entire sky by the author and collaborators (ref. 6, 11, 22).
There are many sources of velocities, so this catalog could
potentially be quite heterogeneous. However, two sources dominate.
One of these is the magnitude-limited Shapley-Ames sample, which
assures the inclusion of all galaxies brighter than 12th magnitude in
the blue passband (ref. 25). There are 1053 Shapley-Ames galaxies
within the velocity limit. The other source was already mentioned: the
all-sky survey in the neutral hydrogen line by the author and
collaborators. This survey was undertaken after a complete
reinspection of photographic atlases of the sky. This survey was
insensitive to gas-deficient systems and has severe incompletion
problems at velocities beyond 2000 kilometers/second (discussed in
ref. 11). However, the virtue of our survey is homogeneous coverage
across the unobscured part of the sky. The neutral hydrogen survey
provides 1515 velocities to the catalog. There is some overlap
between the two principal sources. It is this cumulative sample that
is mapped in the NBG Atlas.
There are three parts to the catalog. The first and by far the largest
section (catalog) provides information about each of the 2367
galaxies. One element of that information is a group affiliation, and
in a second section (groups) there is a reordered listing that
clarifies the composition of each group. The final, very short section
(clusters) identifies the rich clusters of galaxies that delineate the
supercluster complexes mapped in the last two plates of the NBG Atlas.
The text of the atlas is written at a level that can be appreciated by
a wide audience. The material in this catalog and the following
description are of a more technical nature. This catalog is intended
for an audience of professional and motivated amateur astronomers.
