ADC_Keywords: Galaxies, IR ; Redshifts Keywords: galaxies: general - infrared radiation 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. File Summary:

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) 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); 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) 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), 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: * Freedman et al., 2001ApJ...553...47F * Madore & Freedman 1998, in Stellar Astrophysics for the Local Group: VIII Canary Islands Winter School of Astrophysics, ed. A. Aparicio, A. Herrero, & F. Sanchez (Cambridge: Cambridge Univ. Press), 263 * Ferrarese et al., 2000ApJS..128..431F, * Mould et al., 1991ApJ...383..467M * Tully & Shaya, 1984ApJ...281...31T * Aaronson & Mould, 1983ApJ...265....1A * Aaronson et al., 1982ApJ...258...64A and 1982, Cat. VII/75 * Aaronson, Mould, & Huchra, 1980ApJ...237..655A 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). 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) 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). 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.

Note (1): Notes as follows: a = IRAS centroid is on the southeast component of the pair, but both galaxies are within the IRAS beam (Fig. 1); see also Surace, Sanders, & Mazzarella (2004, Cat.
