The AGN magnitude and surface brightness reported in Table 1, columns (2) and (3), were offset by band-dependent constants. The corrected values are given in the new version of Table 1 presented herein. The same photometric offsets were also used in Figure 2, which has incorrect values on the y-axis. The corrected Figure 2 is also shown herein. The rest of the work in this article is otherwise unaffected, and the conclusions remain unchanged. We are grateful to Nancy Levenson for bringing the matter to our attention.
