The bulge fraction (upper-left), the disc scalelength (lower-left), the effective radius of the bulge (upper-right) and the half-light radius of the galaxy (lower-right), obtained using different parametric functions to perform the decomposition (de Vaucouleurs plus exponential on the x-axis and Sérsic plus exponential on the y-axis) are plotted against each other for the 1680 galaxies (in the photometric sample) successfully modelled by the two fitting functions in the i band.
