Abstract:
We present an all-sky catalog of 451 nearby galaxies, each having
an individual distance estimate D≲10Mpc or a radial velocity
VLG<550km/s. The catalog contains data on basic optical and H I
properties of the galaxies, in particular, their diameters, absolute
magnitudes, morphological types, circumnuclear region types, optical
and H I surface brightnesses, rotational velocities, and indicative
mass-to-luminosity and H I mass-to-luminosity ratios, as well as a
so-called tidal index, which quantifies the galaxy environment. We
expect the catalog completeness to be roughly 70%-80% within 8Mpc.

Note (1): The main sources for the classification were 2MASS images
(Jarrett et al., 2000AJ....119.2498J 2000AJ....119.2498J) and high-resolution images
of galaxies from the HST archive (see illustrations and details
in Karachentsev & Karachentseva, 2002, ASP Conf. Ser. 284, 325)
K = Kern, a stellar-like nucleus;
B = Bulge, where a stellar-like nucleus may be hidden because of
strong extinction or steep brightness gradient;
A = Absence of a distinct nucleus.
Note (2): Taken from the Lyon Extragalactic Database (LEDA) or from
Huchtmeier et al. (2000, Cat. J/A+AS/141/469,
2001, Cat. J/A+A/377/801, 2003A&A...401..483H 2003A&A...401..483H);
for some southern
dwarf galaxies, their line widths were measured on the basis of
the H I Parkes Sky Survey (HIPASS, VIII/73) data accessible at
www.atnf.csiro.au .
Note (3): From LEDA, Huchtmeier et al. (2000, Cat. J/A+AS/141/469, 2001,
Cat. J/A+A/377/801, 2003A&A...401..483H 2003A&A...401..483H), or HIPASS (VIII/73).
Note (4): Method used to determine distance as follows:
cep = From the luminosity of Cepheids;
rgb = From the luminosity of the tip of RGB;
sbf = Via fluctuation of surface brightness;
bs = From the luminosity of the brightest stars;
tf = From Tully-Fisher relation;
mem = From membership in the known groups;
h = From the Hubble relation LGVel=H0*D with the mean local
Hubble parameter H0=72km/s/Mpc (Karachentsev et al.,
2003A&A...398..467K 2003A&A...398..467K), coinciding with its global value
(72±8)km/s/Mpc (Freedman et al., 2001ApJ...553...47F 2001ApJ...553...47F).
Note (5): References to the distance estimates and to the galaxy

Note (2): Corrected for galaxy inclination and the Galactic extinction
in the manner adopted in the RC2 (de Vaucouleurs et al., Cat. VII/112
log(A25) = log(Akpc) - 0.20*log(a/b) + 0.09*Ag
Note (3): sin2(i) = [1-(b/a)2]/[1-(b/a)20], where (b/a)0 = 0.07
if MType = 6 or 7, (b/a)0 = 0.12 if MType = 5 or 8,
(b/a)0 = 0.18 if MType = 4 or 9, and (b/a)0 = 0.20 otherwise.
Note (4): RotVel = W50/2*sin(i), corrected for inclination and turbulent
motions according to Tully & Fouque (1985ApJS...58...67T 1985ApJS...58...67T) with
isotropic noncircular motion parameter σz=8km/s; (the
correction for turbulent motions for some dwarf galaxies with
W50≤20km/s leads to negative values of RotVel, and we adopt for
them a formal value RotVel=5km/s).
Note (5): According to Giovanelli et al. (1994AJ....107.2036G 1994AJ....107.2036G) and
Tully et al. (1998AJ....115.2264T 1998AJ....115.2264T), the internal absorption depends
not only on inclination, but also on galaxy luminosity; Basing on the
data by Verheijen (2001ApJ...563..694V 2001ApJ...563..694V) and Karachentsev et al. (1999,
Cat. J/A+AS/139/97), we determined the internal absorption as
ABi=[1.6+2.8(log(RotVel)-2.2)]*log(a/b) if RotVel>42.7km/s, otherwise,
ABi=0 (so, we considered dwarf galaxies to be fully transparent); for
the gas-poor E, S0, dSph galaxies without estimates of W50, the ABi
correction was also ignored.
Note (6): Corrected for ABg and ABi.
Note (7): <SuBr≥(Bmag-ABg-ABi)+5*log(ac)+8.63.
Note (8): log(MHI/MSun)=log(F)+2*log(Dist)+5.37 (Roberts & Haynes,
1994ARA&A..32..115R 1994ARA&A..32..115R)
Note (9): SDHI=4*MHI/π*A25^2.
Note (10): Within its standard diameter S25.
log(M25i/MSun)=2*log(RotVel)+log(ac)+log(Dist)+4.25
(Roberts & Haynes, 1994ARA&A..32..115R 1994ARA&A..32..115R).
Note (11): Determined in section 6. Negative values correspond to
isolated galaxies, and positive values are typical of group members.
Note (12): Main disturber producing the maximum tidal action on the
galaxy; in fact, a collection of galaxies with one and the same
main disturber, and also the positive Theta may be considered as a
separate group (see also notes to Table 1).

Global Notes:
Note (G1): Known catalogs: NGC (N), IC (I), UGC (U, Nilson 1973),
UGCA (UA, Nilson 1974), DDO (D, van den Bergh 1966),
ESO/Uppsala (E, Lauberts 1982), PGC (P, Paturel et al. 1996), and
Karachentsev's lists (KK, KKR, KKH, KKSG, KKs), usually in
chronological preference.
Note (G2): Measured at a level of ∼25mag/arcsec2; for dwarf galaxies
of low surface brightness from the KK lists, their diameters
correspond to the Holmberg system (∼26.5mag/arcsec2).
Note (G3): The NASA Extragalactic Database (NED) is the main source with
additions from the recent publications by Makarova (1999,
Cat. J/A+AS/139/491), Bremnes et al. (1998A&AS..129..313B 1998A&AS..129..313B,
1999A&AS..137..337B 1999A&AS..137..337B, 2000A&AS..141..211B 2000A&AS..141..211B), Parodi et al. (2002,
Cat. J/A+A/388/29), etc.; for some dwarf LSB galaxies their
magnitudes are known with an accuracy of ∼0.5mag only.
Note (G4): From Schlegel et al. (1998ApJ...500..525S 1998ApJ...500..525S); estimates of Ag
for some galaxies situated in the zone of avoidance (for instance,
Maffei I) were made from their individual color.
Note (G5): From the NASA Extragalactic Database (NED) or from recent
sources (Huchtmeier et al., 2000, Cat. J/A+AS/141/469,
2001, Cat. J/A+A/377/801, 2003A&A...401..483H 2003A&A...401..483H;
Makarov et al., 2003A&A...405..951M 2003A&A...405..951M).
Note (G6): With the apex parameters according to Karachentsev & Makarov
(1996AJ....111..794K 1996AJ....111..794K).
