Completeness in the bivariate planes of apparent magnitude and u−r colour (top panels), apparent magnitude and effective surface brightness (middle panels), and apparent magnitude and Sérsic index (bottom panels) for GAMA data after year 1 (left-hand panels), year 2 (middle panels) and year 3 (right-hand panels). Contours show the percentage of galaxies enclosed from out to in, 99, 95, 75, 50 and 5 per cent. Apart from the progression in apparent magnitude over the 3 yr, no other obvious bias is evident.
