Simulated images produced from deconvolutions of the objects shown schematically in Fig. 2. The simulated image before deconvolution is shown in the top right corner of each panel of nine images. Left: deconvolved objects marked by the diamond symbols in the top left of Fig. 2 with high S/N (=100), right: deconvolved objects marked by the diamond symbols in the top right of Fig. 2 with low S/N (=10).
