Erratum 'Dust and Gas in the Magellanic Clouds from the HERITAGE Herschel Key Project. I. Dust Properties and Insights into the Origin of the Sub-mm Excess Emission'

The values of κ_eff,160 given in the original paper are missing a factor of π. This is because the routine used to compute B_λ(T) was the IDL Astronomer User's Library planck.pro and it returns πB_λ(T). The correct values of k_eff,160 are approximately a factor of two larger than the values calculated from full dust grain models and discussed in Section 5.3 of the paper. This difference may be due to the simple models in our paper, which did not include the full physical treatment (e.g., multiple grain sizes/compositions with different temperatures) or, less likely, some issues with the assumptions in the dust grain models. We are carrying out work to investigate such issues for the dust in the Magellanic Clouds (and Milky Way) using more complicated dust grain models and additional observations. (authors)
