Goodness of fit measures for our two-component modelling of the i-band images. The two left-hand panels give results for the 1469 galaxies modelled successfully using a de Vaucouleurs profile for the bulge and an exponential profile for the disc. The two right-hand panels give results for the 1515 galaxies modelled successfully when we use the more general Sérsic profile for the bulge. The two upper panels show results for , the total light in the residual image in units of the total light of the model. The two lower panels give results for , the sum of the absolute values of the individual pixel deviations from the model again in units of the total model luminosity. G₁ and G₂ are plotted against absolute magnitude in the main part of each panel while a histogram of their marginal distribution is given in the inset.
