Erratum: “CO Line Width Differences in Early Universe Molecular Emission-Line Galaxies: Submillimeter Galaxies versus QSO Hosts” (AJ, 131, 2763 [2006])

It has been pointed out to us that in three dimensions the mean angle of randomly oriented disks with respect to the sky plane is h i 1⁄4 30 , and not the 45 assumed in the original paper. This lower angle for the (assumed) random distribution of submillimeter galaxies, coupled with the factor of 2.3 lower mean CO line width for high-z, far-IR-luminous QSO host galaxies relative to the submillimeter galaxies, implies a mean angle with respect to the sky plane for the QSO host galaxies of h iQSO 1⁄4 13 , as opposed to the 18 quoted in the original paper. We thank Pat Hall for bringing this to our attention.
