Several proof corrections were not carried faithfully to the published version of this article. In particular, a central sentence of the abstract should readThis can be achieved by varying the relative bulge-to-disk stellar density while maintaining the same effective bulge-to-disk size ratio.In Astron. J. 121, 820 (2001), there is an erroneous subscript. The heading for column (2) should readearly-late .In addition, in the second paragraph of Astron. J. 121, 820 (2001), ``inclusion of the boundaries'' should read ``inclusion of boundaries,'' i.e., no preexisting set should have been implied; in the second paragraph of Astron. J. 121, 820 (2001), ``when the bulge and the disk contribute equally'' should read ``where the bulge and disk contribute equally,'' referring to position in space rather than time. The same mistake occurs two paragraphs following and in Astron. J. 121, 820 (2001). The publisher regrets any confusion caused by these errors.
