Two-dimensional photometric decomposition of the mock i-band image of the simulated lenticular remnant gS0dE0o100 seen at an inclination θ = 60° obtained with GASP2D. The upper panels (from left to right) show the map of the observed, modeled, and residual (observed−modeled) surface brightness distributions. The lower panels (from left to right) show the ellipse-averaged radial profile of surface brightness, ellipticity, and position angle measured in the observed (black dots with gray error bars) and seeing-convolved modeled image (green solid line) and their corresponding difference. The intrinsic surface-brightness radial profiles of the best-fitting bulge (blue dashed line) and disk (red dotted line) are also shown in both linear and logarithmic scale for the distance to the center of the galaxy.
