Our new methodology enables us to measure, for the first time, a radial gradient in the ellipsoid ratio sigma_z / sigma_R. Random errors in this decomposition are 15% at two disk scale-lengths.4 pages, 3 figures, to appear in the proceedings of "Formation and Evolution of Galaxy Disks", Rome, October 2007, Eds. J.
