Scaling relations of galaxies the baryonic Tully–Fisher relation (left panel), the baryonic mass–size relation (middle panel), and the baryonic angular-momentum relation (right panel). The three panels cover the same dynamic range on the y-axis. The circles and crosses are the same as those in Fig. 4, colour-coded by the effective baryonic surface density Σ_50, bar. The blue and gold solid lines are the best-fit lines for LSD galaxies and HSD galaxies, respectively. The dashed black line in the right panel shows the best-fit line considering all 147 galaxies together.
