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.

Note (7): the following flags are used for logD25 and logR25:
    '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
    'Z'  uncorrected Zwicky magnitudes
    'A'  unexplained flag in record #245 (MAFFEI II)
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".
