Surface brightness profile of EXT8 and various model profiles, both shown versus semi-major axis A. Filled circles are based on star counts, the solid black curve on surface photometry. King (1966) and Wilson (1975) models are drawn with dashed and solid curves. The best-fitting model, a Wilson model with W0 = 7.3, is plotted as a dotted curve.
