(a) Gini coefficient ( G) vs. rotational asymmetry ( A). Dividing lines are drawn between regions of predominantly irregular, spiral, and elliptical types from Capak et al. (2007b). The dashed line between irregular and spiral galaxies is defined as log  A = 2.353log  G + 0.353, while the solid line between spiral and early-type galaxies is defined as log  A = 5.5log  G + 0.825. The dot-dashed line is a cut at log  G = −0.35, used to select early-type galaxies in this paper. (b) Gini coefficient ( G) vs. M ₂₀. The solid line is defined as M ₂₀ = 8.0log  G + 1.1. EROs that have spectral type, , are colored red, and those with are blue. d ( d _GA , d _G , d _GM ) is the perpendicular distance from each point in the diagram to the dividing lines.
