Abstract

On page 16 of the published article, the sentence that begins as, We indeed detect such emission, particularly in the early-time MMT spectrumK, is written incorrectly and would be misleading to a reader. The actual Hα luminosity, LHα, that we estimated from the observed line flux in the spectrum is ∼9.2×1037 to 3.4 ×1038 erg s-1. The "6.7 × 1049 to 2.5 × 1050" written in that passage of the published article is actually referring to the number of Lyman continuum photons, NLyC. This is purely a typographical error. Again, following Martins et al. (2005), NLyC is still equivalent to 1-4 O3 I stars or 4-15 O5 V stars. We stress that the end result of that calculation and discussion are totally unaffected. Additionally, in Sections 2.3 and 4.1 and in Figure 8, we refer to the pre-explosion Hubble Space Telescope WFPC2 images as being from 2006 October 20, whereas these data are from 2007 December 11. Again, this is a typographical error and has absolutely no effect on the detection and characterization of the supernova progenitor candidate. The overall conclusions of the paper remain entirely unchanged.
