Extended Data Fig. 1: 2D decomposition of eUCDs.
From: An evolutionary continuum from nucleated dwarf galaxies to star clusters
First column: Radial surface brightness profile of the UCD and best-fit result of the two-component fitting. All eUCDs can be well-fit with an inner King model and an outer Sérsic model. The total, King, and Sérsic model profiles are shown with red, magenta and green dashed lines, respectively. The grey dashed line is the PSF profile. Error bars represent 1σ uncertainties. The fitting residuals are shown below the source profile. Second column: NGVS u*g′i′ colour composite image. Third column: The g′-band image of UCD, with contours showing the surface brightness at µg′ = 24 to 27 mag arcsec−2. Last column: (data−model) residual map.
