Ratio V/σ as a function of galaxy stellar mass (left panel), maximum rotational velocity (middle panel), and size (right panel). The horizontal dashed lines set the limit between rotation-dominated (blue points above the line) and dispersion-dominated (red points below the line) galaxies. No clear correlation is seen but dispersion-dominated galaxies are mostly massive (>10⁹M_⊙), slowly rotating (≤50 km s^-1), and compact.
