Erratum: ``Intergalactic Photon Spectra from the Far-IR to the UV Lyman Limit for 0 < z < 6 and the Optical Depth of the Universe to High-Energy Gamma Rays'' (ApJ, 648, 774 [2006])
Abstract
Table 1 in our paper had erroneous numbers for the coefficients fitting the parametric form for the optical depth of the universe to γ-rays, τ. The correct values for these parameters as described in the original text are given in the table below for various redshifts for the baseline model (upper row) and fast evolution (lower row) for each individual redshift. The parametric approximation holds for 10-2<=τ<=102 and Eγ<~2 TeV for all redshifts, but also up to ~10 TeV for z<=1.
