ADC_Keywords: Galaxies, IR ; Redshifts Abstract: Complete IRAS Observations and redshifts are reported for all sources identified in the IRAS Bright Galaxy Survey - Part II (hereafter referred to as BGS2). Source positions, radial velocities, optical magnitudes, and total flux densities, peak flux densities, and spatial extents at 12, 25, and 100um are reported for 288 sources having 60um flux densities >5.24Jy, the completeness limit of the original Bright Galaxy Survey [Soifer et al. (1989AJ.....98..766S)], hereafter referred to as BGS1. These new data represent the extension of the IRAS Bright Galaxy Survey to southern declinations, Dec≲-30deg, and low Galactic latitudes, 5deg<|b|≤30deg. Although the sky coverage of the BGS2 (∼19935deg^2) is 37% larger than the sky coverage of the BGS1, the number of sources is 8% smaller due primarily to large scale structure in the local distribution of galaxies. Otherwise, the sources in the BGS2 show similar relationships between number counts and flux density as observed for the 313 sources in the BGS1. The BGS2 along with the earlier BGS1, represents the best sample currently available for defining the infrared properties of galaxies in the local (z≲0.1) Universe. File Summary:

Note on Name: The common catalog name has been taken in decreasing priority order from the NGC, UGC, ESO, IC, A, MCG, Zwicky catalog, Zwicky lists, Markarian, Arp-Madore, and IRAS catalogs. In table1b.dat, source IR 19542+1110 (RA=19:54:13.3, DE=+11:10:59) has a tentative identification of Halpha+[NII]; source not listed in NED. Note on RAh: All positions (1950) are taken from the PSC Version 2 II/125 except for those galaxies from Rice et al VII/109 where the positions were taken from the RC2. Note on cz: The heliocentric radial velocity (z=Delta(lambda(opt))/Lambda(opt) Note on u_cz: For those galaxies with no published redshift at the time the current survey was begun (1991), a velocity was measured from optical spectra obtained with either the UH 2.2 m telescope, or the 2.15 m telescope in Argentina. The typical uncertainty in the measured redshifts is ± 30 km/s. All other redshifts are taken from NED. Note on D: Either a "primary distance" from Sandage & Tammann VII/51 catalog or a Fisher-Tully distance taken from either Aaronson et al. VII/75, Aaronson & Mould (1983ApJ...265....1A), or Tully & Shaya (1984ApJ...281...31T) (adjusted to a Virgo distance of 17.6 Mpc). For all other sources (those with no entry in D), the distance was calculated from CZ using the "Virgo-centric flow" model of Aaronson et al. (1982ApJ...258...64A) with an adopted distance to Virgo of 17.6 Mpc (corresponding to H0=75km/s/Mpc at large distances). Note on m: The "optical" magnitude, as listed in the "object data" window in NED. For those few sources with more than one identified object within ≲ 40" radius of the IRAS position (e.g. multiple "nuclei," close merger pairs), only the magnitude of the brightest object has been given. Note on S12, S25, S60, S100: Best estimate for the total IRAS flux density as determined from coadded data using ADDSCAN/SCANPI. For the six sources not detected at 12 um, the reported upper limit is taken to be three times the rms noise of the coadded data. For source ESO 452-G005 (RA=16:28:33.5, DE=-27:59:48), it was impossible to estimate the 100 um flux. Note on n_S12, n_S25, n_S60, n_S100: An asterisk (*) indicates that the flux density was taken directly from Rice et al. VII/109, while a hash mark (#) indicates that the source was partially blended with a nearby source, or that the baseline was somewhat uncertain and the listed flux has a correspondingly larger associated uncertainty, typically ±10%-20% for sources at |b|>10deg, and ±10%-30% for sources at |b|=5-10deg. Note on sS12, sS25, sS60, sS100: The extent code: U = unresolved source, in which case the flux is taken as the point-source template fit; U+ = marginally resolved, and R = resolved, in which case the flux density is the integrated flux for the source.

Note on Name: In table2b.dat, source IR 19542+1110 has a tentative identification and is not listed in NED. Note on n_Band: An asterisk (*) indicates that the flux density was taken directly from Rice et al. VII/109, while a hash mark (#) indicates that the source was partially blended with a nearby source, or that the baseline was somewhat uncertain and the listed flux has a correspondingly larger associated uncertainty, typically ±10%-20% for sources at |b|>10deg, and ±10%-30% for sources at |b|=5-10deg. Note on Templ: The estimate of the flux density from the amplitude of the point-source template. Note on Peak: The peak flux density in the average scan of the source (without the baseline fit used to determine the template fit). Note on W25, W50: No attempt has been made to deconvolve the point-source width.
