Abstract:
    We present a large robust sample of 1503 reliable and unconfused 70um
    selected sources from the multiwavelength data set of the Cosmic
    Evolution Survey. Using the Spitzer IRAC and MIPS photometry, we
    estimate the total infrared (IR) luminosity, LIR (8-1000um), by
    finding the best-fit template from several different template
    libraries. The long-wavelength 70 and 160um data allow us to obtain a
    reliable estimate of LIR, accurate to within 0.2 and 0.05dex,
    respectively. The 70um data point enables a significant improvement
    over the luminosity estimates possible with only a 24um detection. The
    full sample spans a wide range in IR luminosity,
    LIR~10^8^-10^14^L_{sun}_, with a median luminosity of
    10^11.4^L_{sun}_. We identify a total of 687 luminous, 303
    ultraluminous, and 31 hyperluminous infrared galaxies (LIRGs, ULIRGs,
    and HyLIRGs) over the redshift range 0.01<z<3.5 with a median redshift
    of 0.5. Presented here are the full spectral energy distributions
    (SEDs) for each of the sources compiled from the extensive
    multiwavelength data set from the ultraviolet (UV) to the
    far-infrared. A catalog of the general properties of the sample
    (including the photometry, redshifts, and LIR) is included with this
    paper.

Description:
    The imaging data used for this study were obtained as part of the
    HST-COSMOS project, using the F814W filter (I band) during 2003-20005
    (Scoville et al. 2007ApJS..172...38S). To supplement the ACS coverage,
    follow-up observations have been obtained across the entire spectrum
    using both space- and ground-based facilities (Spitzer/IRAC and MIPS
    in 2006-2008; GALEX in 2004, XMM-Newton in 2004-2005; Chandra in
    2006-2007; CFHT in 2003-2007; Subaru in 2004-2005; UKIRT in 2004-2007;
    VLA in 2003-2005). A complete description of the COSMOS data sets can
    be found in Scoville et al. (2007ApJS..172....1S).
