Abstract:
IRAS flux densities, redshifts, and infrared luminosities are reported
for all sources identified in the IRAS Revised Bright Galaxy Sample
(RBGS), a complete flux-limited survey of all extragalactic objects
with total 60µm flux density greater than 5.24Jy, covering the
entire sky surveyed by IRAS at Galactic latitudes |b|>5°. The RBGS
includes 629 objects, with median and mean sample redshifts of 0.0082
and 0.0126, respectively, and a maximum redshift of 0.0876. The RBGS
supersedes the previous two-part IRAS Bright Galaxy Samples (BGS1+BGS2)
which were compiled before the final (Pass 3) calibration of the IRAS
Level 1 Archive in 1990 May.

Note (1): Taken in decreasing priority order from the NGC, UGC, ESO, IC, A,
MCG, CGCG, Zwicky compact galaxies, Markarian, and IRAS catalogs.
Note (2): Note on Name as follows:
N = A "new" RBGS object that was not included in the compilation of
the BGS1 (Soifer et al. 1989AJ.....98..766S 1989AJ.....98..766S) or
BGS2 (Sanders et al. 1995, Cat. J/AJ/110/1993)
1 = From the BGS1
2 = From the BGS2
Note (3): Names from the IRAS Faint Source Catalog (FSC) are given using
the standard "F" prefix; if the source is not in the FSC, the name
from the Point Source Catalog (PSC) is given, which has no letter
prefix. IRAS source names are based on equinox B1950.0 coordinates.
Names from the IRAS Faint Source Catalog Rejects (FSCR) are given
using the standard "Z" prefix. (NGC 4151 is the only FSCR object in
the RBGS; see section 2.) IRAS catalog names are not listed for a few
very large galaxies, because entries in the IRAS catalogs do not
represent the total flux and generally correspond only to the nucleus
or other bright component.
Note (4): Note on IRAS name as follows:
R = Large galaxy for which the total flux densities derived from IRAS
images were published by Rice et al. (1988, Cat. VII/109) or
Rice (1993AJ....105...67R 1993AJ....105...67R); the Rice et al. values are adopted
here only in cases listing an "R" value for columns M12F, M25F,
M60F, and M100F; see text for details.
* = Object located in a region of the Milky Way, LMC, or SMC with
high source confusion.
Note (5): Transformed from equinox B1950.0 coordinates published in the
IRAS FSC (version 2.0) or PSC (version 2), as indicated in the IRAS
column. These coordinates correspond to the centroid of the IRAS
positional uncertainty ellipse as superposed on the Digitized Sky
Survey fields shown in Fig. 1. Exceptions are for the large galaxies
NGC 55, SMC, NGC 300, LMC, NGC 6744, and NGC 6822, whose positions are
taken from Rice et al. (1988, Cat. VII/109).
Note (6): From Surace, Sanders, & Mazzarella (2004, Cat. J/AJ/127/3235).
A listing here indicates that the infrared source contains two or more
objects that were confused in one or more of the IRAS detectors. The
high-resolution image restoration algorithm HIRES (Aumann, Fowler, &
Melnyk, 1990AJ.....99.1674A 1990AJ.....99.1674A) was applied to these sources in an
attempt to resolve flux from individual galaxies.
R = source was resolved into two or more components, resulting in new
IRAS positions and fluxes;
* = Source was resolved, but the IRAS position lies between the two
galaxies as seen on the DSS;
S = Source was partially resolved into two or more components, and
fluxes were estimated for each object, but no new reliable
positions were derived;
U = HIRES was unsuccessful at resolving separate components; see
Surace et al. (2004, Cat. J/AJ/127/3235) for detailed HIRES
results for these objects.
Note (7): IR size flags as follows:
U = Unresolved
M = Marginally extended
R = Resolved
Note (8): Best flux estimate method flags as follows:
Z = Zero crossing
I = In-band total
T = Template fit
P = Peak value
S = Deconvolution with SCLEAN (see Appendix)
R = From Rice et al. (1988, Cat. VII/109)
Note (9): Confusion type flags as follows:
c = Cirrus;
g = Nearby galaxy;
n = Excessive noise;
b = Blended object.
Note (10): The source for the redshift is given in col. (2) of Table 2
as a 19-digit reference code from NED. In cases where either a
millimeter (e.g., CO) or HI 21cm line measurement has been reported,
we have chosen to adopt these redshifts given that they better reflect
the systemic velocity of the galaxy, as opposed to optical
measurements, which are often biased (typically blueshifted) because
of optical depth effects.
Note (11): Metric ("proper") distance is listed, not luminosity distance.
For most objects this was calculated from cz using the cosmic
attractor model outlined in Appendix A of Mould et al.
(2000ApJ...529..786M 2000ApJ...529..786M), using H0=75km/s/Mpc and adopting a flat
cosmology in which ΩM=0.3 and ΩΛ=0.7 (which
corresponds to q0=-0.55).
Note (12): References for the adopted primary and secondary distance
indicators are:

The flags are:
P = Distance is not computed by correcting the heliocentric redshift
using the cosmic attractor model, but comes from a direct
primary distance measurement;
S = A direct secondary distance measurement;
V = The cosmic attractor flow model places the object within the Virgo
Cluster at a distance of 15.3 Mpc;
G = Cosmic attractor flow model places the object within the
Great Attractor.
Note (13): Determined using the prescription described in Appendix B of
Cataloged Galaxies and Quasars Observed in the IRAS Survey (1989).
Note (14): Determined using the fluxes in all four IRAS bands (Perault,
1987, Ph.D. thesis, Univ. Paris) see also Table 1 in Sanders & Mirabel
1996ARA&A..34..749S 1996ARA&A..34..749S).
Note (15): From catalogs of interacting galaxies (IGs) or active galactic
nuclei (AGNs).

Note (1): These objects were listed in Table 1(b) of BGS1 (Soifer et al.,
1989AJ.....98..766S 1989AJ.....98..766S) as having Snu(60um)<5.24Jy. However, they were
also included in the main BGS1 catalog listing [Table 1(a)], because
of their presence in an earlier compilation (Soifer et al.,
1987ApJ...320..238S 1987ApJ...320..238S). Since some readers may have been confused
regarding the status of these objects, these sources are listed here
again and omitted in Table 1 of this work to clarify their status.
