Scientific paper

Complete IRAS Observations and redshifts are reported for all sources identified in the IRAS Bright Galaxy Survey-Part II (hereafter referred to as BGS_2_). Source positions, radial velocities, optical magnitudes, and total flux densities, peak flux densities, and spatial extents at 12, 25, and 100 ,microns are reported for 288 sources having 60 micron flux densities > 5.24 Jy, the completeness limit of the original Bright Galaxy Survey [Soifer et al., AJ, 98,766(1989)], hereafter referred to as BGS_1_. These new data represent the extension of the IRAS Bright Galaxy Survey to southern declinations, δ<~-30^deg^, and low Galactic latitudes, 5^deg^<|b|<30^deg^. Although the sky coverage of the BGS_2_ (~19 935 deg^2^) is 37% larger than the sky coverage of the BGS_1_, the number of sources is 8% smaller due primarily to large scale structure in the local distribution of galaxies. Otherwise, the sources in the BGS_2_ show similar relationships between number counts and flux density as observed for the 313 sources in the BGS_1_. The BGS_2_ along with the earlier BGS, represents the best sample currently available for defining the infrared properties of galaxies in the local (z <~ 0.1) Universe.
