Results from our single Sérsic fitting analysis for galaxy CATAID 300986. The rows correspond to the photometric bands: (from top to bottom) KiDS g, KiDS r, KiDS i, and VIKING Z. From left to right columns: the original 50 × 50 arcsec² image, its GALFIT model with its associated effective radius ellipse, the residual image (original – model) –in units of surface brightness mag arcsec², that is the reason why one colour bar per band– and the residual image again in units of counts with a single colour bar which is shared by all the images in the last column.
