Abstract:
This study presents a highly complete and reliable IRAS 60-micron
galaxy catalog covering 82 percent of the sky. IRAS color conditions
are used to exclude galactic sources, including the remaining cirrus
sources. All sources flagged as extended, confused, or having a poor
correlation coefficient with a point-source template are examined with
the raw IRAS data and accurate fluxes determined using mapping
routines. The completeness, reliability, and flux accuracy of the
catalog are discussed. Identifications are made with existing optical
galaxy catalogs and with galaxy redshift surveys in the literature. It
is estimated that redshifts are available for 79 percent of the
galaxies in the catalog with V less than 5000km/s, and the 3D
distribution of such galaxies is displayed. The dipole component of
the surface-brightness distribution of galaxies in the catalog is
discussed.

Note (1): Extended source flags as follows:
1 = flagged as confirmed extended source
2 = in SSS Catalog
3 = in Large Galaxy Catalog
4 = addscan flux
5 = addscan flux, source is double
6 = coadd flux
7 = coadd flux, source is double
Note (2): The cirrus flag measures the number of sources detected only
at 100µm in a 1-°2 area around the source
Note (3): 1, A-M
Note (4): 0-9, A C D E F
Note (5): -9999 means velocity exists but not released yet
