Abstract:
Companion galaxy environment for a subset of 78 bright and nearby
barred galaxies from the Shapley-Ames Catalog is presented. Among the
spiral barred galaxies, there are Seyfert galaxies, galaxies with
circumnuclear structures, galaxies not associated with any large-scale
galaxy cloud structure, galaxies with peculiar disk morphology
(crooked arms), and galaxies with normal disk morphology; the list
includes all Hubble types. The companion galaxy list includes the
number of companion galaxies within 20 diameters, their Hubble type,
and projected separation distance.

The first digit specifies one of seven regions in T88, and the
second digit identifies a specific cloud within the general region;

Note (2): New Cepheid distance has been determined to be 11.7Mpc
(Leonard et al., 2003ApJ...594..247L 2003ApJ...594..247L). This new distance does
not modify any of the analysis in this paper.

Note (1): From Huchtmeier & Richter, 1989, Cat. VIII/68.
Note (2): From Tully, 1987ApJ...321..280T 1987ApJ...321..280T.
Note (3): Extracted from NED (angular separation and systemic velocity) and
(members of groups). Nomenclature according to catalog:
E = ESO;
ED = ESOD;
F = FGC;
I = IC;
LE = LEDA;
M = MCG;
N = NGC;
SB = SBS;
SD = SDSS;
U = UGC;
UA = UGCA;
US = USGC.
Note (4): Note on Comp:
IRAS1214 = IRAS 12140+6947;
KUG1207 = KUG 1207+367;
MCG0260 = MCG -02-60-010;
N5846:XX = NGC 5846[ZM98]00XX;
[RC3]112 = [RC3] 1127.3+1642.
US:U480 NED 29 = NGC 4214.
Note (5): Calculated from angular separation (from NED) and distance.
SB1147 = SBS 1147+520;
SB1211 = SBS 1211+540;
SD:J143 = SDSS J143950.03-004222.9;
SD:J1506 = SDSS J150634.25+001255.7;
2MASXJ07 = 2MASX J07084902+1845271;
2MASXJ124 = 2MASX J12412460+1210328;
2MASXJ1457 = 2MASX J14575308+0056035.
Note (6): Separation estimated from angular separation on the plane of
the sky (from NED) but without redshift or systemic velocity
information of NGC 6908; alignment is probably a chance superposition
since the Hα image from NGC 6907 shows no emission from NGC 6908
(Garcia-Barreto et al., 1996RMxAA..32...89G 1996RMxAA..32...89G).

Global notes:
Note (G1): Main characteristics are as follows:
Sy = Seyfert type;
CNS = circumnuclear structure;
PM = peculiar disk morphology;
NA = galaxies not associated with any substructure, according to
Tully (1987ApJ...321..280T 1987ApJ...321..280T, 1988, Cat. VII/145
refer to Chap. 1 for a brief description when a galaxy is
associated to a group or spur);
ND = normal disk.
