Correlation residuals from the mean relation at fixed virial quantity for the Shellflow, SCII, MAT, and UMa samples. Symbols are as in Fig. 3. Galaxies of all shapes and types (barred and unbarred, early and later types) obey the same surface brightness independent scaling relations. The residual distribution for ﹩\Delta \mathrm{log}\,V/ \Delta \mathrm{log}\,R﹩ of all three samples is flat for barred and unbarred galaxies of all Hubble types and luminosities. The middle figures show a weak correlation between L and R, and the figures on the right side recast the VL relation in its differential form.
