Simulated distributions (1000 objects each) of projected-2D to intrinsic-3D size ratios for four different galaxy types. The intrinsic shape distributions of the four types are given in Table 1. The blue histograms represent projected major axis sizes (﹩a^{\prime} ﹩) compared to intrinsic median sizes (r_med), and red histograms show circularized sizes (R_e).
