The properties of dusty tori in active galactic nuclei can be derived from the comparison of their observed Spectral Energy Distributions (SEDs) and models describing the dust in the pc-to-kpc range from the nucleus. The work presented here makes use mostly of publicly available datasets for the constructions of the observed SEDs, namely SDSS, 2MASS and SWIRE data. The torus model used is that introduced by Fritz, Franceschini and Hatziminaoglou (2006). Models with low equatorial optical depth, tau(9.7), are introduced and the results are compared with those derived using the "traditional" (tau(9.7) > 1.0) models. Properties such as the size of the tori, the mass of dust, the infrared (IR) luminosity and other quantities are derived. Objects with 70 micron detections, representing 25% of the sample, are studied separately, as they provide useful information on the star formation activity, and the relative AGN and starburst contribution to the IR luminosity is estimated.
