ABSTRACT
We report redshifts, magnitudes, and morphological classifications for
5369 galaxies with m_B_ <= 15.5 and for 57 galaxies fainter than this
limit, in two regions covering a total of 1.70 sr in the southern celestial
hemisphere. The galaxy catalog is drawn primarily from the list of
nonstellar objects identified in the Hubble Space Telescope Guide Star
Catalog (GSC). The galaxies have positions accurate to ~1" and magnitudes
with an rms scatter of ~0.3 mag. We compute magnitudes (m_SSRS2_) from the
relation between instrumental GSC magnitudes and the photometry by Lauberts
& Valentijn. From a comparison with CCD photometry, we find that our system
is homogeneous across the sky and corresponds to magnitudes measured at the
isophotal level ~26 mag arcsec^-2^. The precision of the radial velocities
is ~40 km s^-1^, and the redshift survey is more than 99% complete to the
m_SSRS2_ = 15.5 mag limit. This sample is in the direction opposite that of
the CfA2; in combination the two surveys provide an important database for
studies of the properties of galaxies and their large-scale distribution in
the nearby universe.
Key words: galaxies: distances and redshifts-galaxies: photometry
