CDROM/AJ/V110/P1993 IRAS Bright Galaxy Survey. II (Sanders+ 1995) ================================================================================ The IRAS Bright Galaxy Survey - Part II: Extension to Southern Declinations (Dec <= -30), and Low Galactic Latitudes (5 < |b| <= 30 deg) D. B. Sanders, E. Egami, S. Lipari, I. F. Mirabel, & B. T. Soifer <1995, AJ, 110, 1993> =1995AJ....110.1993S ================================================================================ 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 100 um are reported for 288 sources having 60 um 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 BGS1. These new data represent the extension of the IRAS Bright Galaxy Survey to southern declinations, Dec <~ -30 deg, and low Galactic latitudes, 5 deg < |b| <= 30 deg. Although the sky coverage of the BGS2 (~19 935 deg^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.

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. RAh: All positions (1950) are taken from the PSC Version 2 except for those galaxies from Rice et al (1988, ApJS, 68, 91) where the positions were taken from the RC2. cz: The heliocentric radial velocity (z = Delta(lambda(opt))/Lambda(opt) 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. D: Either a "primary distance" from Sandage & Taumann (1981; A Revised Shapley-Ames Catalog of Bright Galaxies (Carnegie Institution, Washington, DC)) or a Fisher-Tully distance taken from either Aaronson et al (1982, ApJS, 50, 241), Aaronson & Mould (1983, ApJ, 265, 1), or Tully & Shaya (1984, ApJ, 281, 31) (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. (1982, ApJ, 258, 64) with an adopted distance to Virgo of 17.6 Mpc (corresponding to H0 = 75 km/s/Mpc at large distances). 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. 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. n_S12, n_S25, n_S60, n_S100: An asterisk (*) indicates that the flux density was taken directly from Rice et al. (1988, ApJS, 68, 91), 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 correspondignly larger associated uncertainy, typically +/- 10%-20% for sources at |b| > 10 deg, and +/- 10%-30% for sources at |b| = 5-10 deg. s_S12, s_S25, s_S60, s_S100: 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. -------------------------------------------------------------------------------- Byte-by-byte Description of file: table2a.dat table2b.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1-15 A15 --- Name *Name as given in table 1 16-19 I4 um Band Wavelength for the following data 20 A1 --- n_Band *[*#] Band note flag 21 1X --- --- Blank 22-23 A2 --- Res Resolution code, R or U+, as in table 1 24-33 F10.2 Jy Total The total flux density from table 1 34 1X --- --- Blank 35 A1 --- l_Templ [<] Limiting character for Templ 36-41 F6.2 Jy Templ *[]?

If Name is blank, the following data fields are continuations for the previous object. In table2b.dat, source IR 19542+1110 has a tentative identification and is not listed in NED. n_Band: An asterisk (*) indicates that the flux density was taken directly from Rice et al. (1988, ApJS, 68, 91), 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 correspondignly larger associated uncertainy, typically +/- 10%-20% for sources at |b| > 10 deg, and +/- 10%-30% for sources at |b| = 5-10 deg. Templ: The estimate of the flux density from the amplitude of the point-source template. Peak: The peak flux density in the average scan of the source (without the baseline fit used to determine the template fit). W25, W50: No attempt has been made to deconvolve the point-source width. -------------------------------------------------------------------------------- ================================================================================ (End) Lee Brotzman [ADS] 19-Feb-1996
