Abstract:
    This paper is the second part of a work investigating the properties
    of dusty tori in active galactic nuclei (AGN) by means of
    multicomponent spectral energy distribution (SED) fitting. It focuses
    on low-luminosity, low-redshift (z≤0.25) AGN selected among emission
    line galaxies in the overlapping regions between Spitzer Wide-area
    Infrared Extragalactic Survey (SWIRE) and Sloan Digital Sky Survey
    Data Release 4 as well as X-ray, radio and mid-infrared selected type
    2 AGN samples from the literature. The available multiband photometry
    covers the spectral range from the u band up to 160um. Using a
    standard chi2 minimization, the observed SED of each object is fit
    to a set of multicomponent models comprising a stellar component, a
    high optical depth (tau9.7≥1.0) torus and cold emission from a
    starburst (SB). The torus components assigned to the majority of the
    objects were those of the highest optical depth of our grid of models
    (tau9.7=10.0). The contribution of the various components (stars,
    torus, SB) is reflected in the position of the objects on the Infrared
    Array Camera (IRAC) colour diagram, with star-, torus- and
    SB-dominated objects occupying specific areas of the diagrams and
    composite objects lying in between.
