Abstract:
We present a new catalogue, the Imperial IRAS-FSC Redshift Catalogue
(IIFSCz), of 60303 galaxies selected at 60um from the IRAS Faint
Source Catalogue (FSC). The IIFSCz consists of accurate position,
optical, near-infrared and/or radio identifications, spectroscopic
redshift (if available) or photometric redshift (if possible),
predicted far-infrared (FIR) and submillimetre (submm) fluxes ranging
from 12 to 1380um based upon the best-fitting infrared template. About
55% of the galaxies in the IIFSCz have spectroscopic redshifts, and
a further 20% have photometric redshifts obtained through either the
training set or the template-fitting method. For S(60)>0.36Jy, the
90% completeness limit of the FSC, 90% of the sources have either
spectroscopic or photometric redshifts. Scientific applications of
the IIFSCz include validation of current and forthcoming infrared and
submm/mm surveys such as AKARI, Planck and Herschel, follow-up studies
of rare source populations, large-scale structure and galaxy bias,
local multiwavelength luminosity functions and source counts.
The catalogue is publicly available at
