Abstract:
    We derive the properties of dusty tori in active galactic nuclei from
    the comparison of observed spectral energy distributions (SEDs) of
    SDSS quasars and a precomputed grid of torus models. The observed SEDs
    comprise SDSS photometry, Two-Micron All-Sky Survey J, H and K data,
    whenever available, and mid-infrared (mid-IR) data from the Spitzer
    Wide-area InfraRed Extragalactic Survey.

Description:
    Coordinates, redshifts, SDSS (ugriz) and 2MASS (JHK) photometry, IRAC
    and MIPS fluxes for the 278 SWIRE/SDSS quasars in the SWIRE EN1, EN2
    and Lockman fields, ordered by RA.
