Distribution ofM (left), I (middle), and D (right) for different types of massive galaxies. The bars at the top represent the median values of M, I, and D for different galaxy types. It is evident that from SPHs to IRRs, the I of galaxies gradually increases, and the D also gradually increases. There are significant differences in the M, I, and D parameters among different categories of galaxies, which indirectly proves the effectiveness of our classification. (SPH: blue, ETD: orange, LTD: yellow, IRR: purple).
