The single Sérsic model fit parameter distributions for the control sample in grey, overplotted by those for the AGN hosts in blue. The top row shows the Sérsic index distributions, the middle row shows the effective radii distributions in units of kpc and the bottom row shows the axial ratio distributions. These distributions have been normalized so that the area under each histogram is equal to one in order to facilitate comparison between the AGN host sample and the much larger control sample. They reveal trends for the AGN hosts to have higher Sérsic indices at z > 1.5. We do not find any significant evidence that the effective radii of the AGN hosts and control samples differ. However, we do report that the axial ratio distributions of the two populations are inconsistent in the 1.5 < z < 2 bin, with the AGN hosts displaying a distribution with rounder systems than the control sample.
