摘要
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 mu m are reported for 288 sources having 60 mu m 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, delta less than or similar to 30 degrees, and low Galactic latitudes, 5 degrees<\b\less than or equal to 30 degrees. Although the sky coverage of the BGS(2)(similar to 19935 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(1) represents the best sample currently available for defining the infrared properties of galaxies in the local (z less than or similar to 0.1) Universe.
