Comparison of the parameters obtained using the different photometric methods explained in Sect. 5: the x-axes correspond to the 1D fit and y-axes to the 2D GALFIT model. The upper panels compare the Sérsic n-values (upper left) and axis ratios b/a (upper right), whereas the lower panels compare the r′-band magnitudes m_r′ (lower left) and the effective radii R_e (lower right). The differences in the position angles obtained by the two methods are indicated with gray scale colors in the upper right panel; dark colors correspond to a large difference, and light colors to a small difference. The most obvious difference appears between the b/a-values, which are systematically closer to unity when calculated using the 1D method. The galaxies which have a nucleus are marked in red. The median differences (n_2d−n_1d, b/a_2d−b/a_1d, m_r′,2d−m_r′,1d, 2 × (R_e,2d−R_e,1d)/(R_e,2d + R_e,1d)), and the corresponding median absolute differences (MAD = Median(|Median(x_i)−x_i|)), where x_i is the difference between 2D- and 1D-measurements) are reported in the upper left corner of the plots.
