Residuals of the modelled or estimated RAR from the relation (20) as a function of the global properties of the galaxies. Left, middle and right columns: RG, QUMOND, and DMS residuals, respectively. From top to bottom the residuals are plotted against the total baryonic mass, bulge effective radius, bulge effective surface brightness, disk-scale length, central disk surface brightness, and total gas fraction. To guide the eye, solid squares with error bars show the means and standard deviations of binned residuals.
