Description Summary of the paper:
A catalog of 2810 nearby galaxies has been prepared. The conditions
for an inclusion into the catalog ensure that most galaxies for which
the effect of the overdensity of the Virgo cluster on their observed
redshifts is not negligible are listed. Three main entities define the
catalog:
1) a magnitude-limited catalog with BT <= 13.4mag
2) a volume-limited catalog with V0 <= 500 km/s, and
3) a Virgo catalog for galaxies within a 10deg-cone around M87
limited at BT <= 14.95mag
In correspondence to a virgocentric nonlinear flow model (Silk, 1974,
1977), distances are calculated for all galaxies in the catalog with
known redshifts. A 95% redshift coverage outside the 10deg-cone around
M87 and a 73% coverage within this cone provide the same coverage in
computed distances. Two sets of distances are listed resulting from
two sets of parameters adopted in the model. They are characterized by
a local infall motion towards Virgo of vVC = 220 km/s and vVC = 440
km/s, thus bracketing most published determinations of vVC. Distances
are in units of the Virgo cluster distance and independent of any
assumption on Ho. In addition to the positions, the recession
velocities and the calculated distances, morphological types,
diameters, axis ratios, apparent blue magnitudes, and
absorption-corrected luminosities based on rVC = 21.7Mpc are listed as
well.

Note (1): (Erratum note)
Four galaxies should be excluded from this catalog:
NGC 1428, UGC 2689, UGC 5247 and A0524+07.
The morphology of NGC 1428 suggests that it is a member of the Fornax
cluster. The velocity in Jones and Jones (1980, source 61) supports
this assumption. It is therefore regarded as the more probable
velocity than the low velocities cited in source 33 and 35. The
galaxies UCC 2689 and UGC 5247 are also judged to be more distant than
implied by their velocities. As these three galaxies are fainter than
the required magnitude limit of this catalog, they should be excluded.
The galaxy with the coordinates RA = 05 24.8 and Dec = 07 29 is not
visible on the POSS prints.

'A' means that logD25 is derived from effective aperture diameter
(ref.39)
'B' for estimations from the VCC (ref.BST)
Note (8): the publication lists the velocity corrected for the solar
motion with respect to the local group
Note (9): the flags are
'P' photographic magnitudes

Note (10): the correction for galactic absorption Ao is unreasonably
large for galaxies flagged with an '*'. The colon and question marks
indicate larger uncertainties.
Note (11): Distances are expressed in units of the Virgo Cluster (VC)
distance. The models are characterized by a local infall motion
toward Virgo of 220km/s and 440km/s respectively.
Note (12): galaxies of the Local Group are adopted from Kraan-Korteweg
and Tamman (1979), assuming a distance of the Virgo cluster of
21.7Mpc.

Historical Notes:
* The original tape was received at CDS in 1987 from the author
* 23-Aug-1995: (at CDS) The original version with 3 lines per entry
was converted into a version with all parameters on a single line,
and the standardized description was added. During this process, a
few errors were detected and corrected:
=> misaligned data and/or missing decimal points have been corrected
in records 675, 869, 1314, 1513, 1516, 1573, 1745, 2786 ;
=> an extra digit in u_BT column existed and was removed
(replaced by a blank) in the two records:
#2517 (NGC 6500), digit '2';
#2518 (NGC 6501), digit '0';
=> The four galaxies listed in the Errata have been flagged in
byte 11.
The references listed in the publication were gathered in the
file "refs".
