Loadings corresponding to the first two principal components are presented for each of our UDG, LSB, and dIrr galaxy samples, which account for at least 80% of the variation in the data. Parameters considered in this analysis from top to bottom are as follows: the ratio of stellar central surface density-to-exponential stellar scale radius (Σ₀/R_D), stellar mass (M_*), HI mass (M_HI), the ratio of stellar radial-to-vertical velocity dispersion (σ_r/σ_z), asymptotic velocity (V_∞), the compactness parameter (V_∞/(R_c/R_D)), stellar velocity dispersion (σ), and specific angular momentum (j_*).
