Comparison between the mass-weighted structural parameters obtained from a single Sérsic component GALFIT 2D fitting technique in this work and the light-weighted estimates of van der Wel et al. (2012). Top row: position angle (left) and axis ratio (right). Bottom row: effective radii (left) and Sérsic index (right). In all four panels, the black symbols indicate galaxies with reliable fits in vdW12, while green ones mark galaxies with reliable fits in this work, but not in vdW12. The blue line is the one-to-one relation. For clarity, only a few points with extremely large error bars have been omitted from this plot. The mass-weighted structural parameters obtained in this work are in good agreement with the light-weighted estimate of vdW12, especially for the axis ratio and the position angle. The majority of galaxies in the sample have mass-weighted effective radii smaller than the light-weighted value, and Sérsic index larger than the estimate of vdW12.
