Comparison between single King, single Sérsic, and King+Sérsic model fitting of a possible eUCD: NGVS-UCD783. The surface brightness profile of NGVS-UCD783 is more like that of a power law. Visual inspection of the contour image shows a potential envelope. Both the single King concentration index c > 2 and the single Sérsic index n > 6 pass our criteria.
