Bulge-lense-disc decomposition performed to an S0-like remnant with an n ~ 1 bulge (model gSbgSbo9). Solid black line: total surface brightness profile in the K band. Red solid line: contribution of the old stars to the total profile. Light blue solid line: contribution of the young stars to the total profile. Red dashed line: fitted bulge (n ~ 1.0). Green dashed line: fitted lense component. Blue dashed line: fitted disc. We have overplotted the limiting magnitude and the minimum and maximum radii considered in the decomposition (dotted straight lines). The subframes of each panel show the artificial K-band images of the remnant for face-on and edge-on views, using a logarithmic greyscale to highlight the substructures at the centre (in particular, the flattened, disc-shaped bulge). The field of view is 50 kpc×50 kpc. (A colour version is available in the electronic edition.)
