Example of deconvolution for a crowded field containing a mix of point sources and extended sources. Left: simulated E-ELT image using the PSF available from ESO (Fig. 8). The image contains 1000 randomly placed stars and 20 extended sources represented by elliptical Sersic profiles. Middle: the deconvolved image, where the PSF (i.e., the target PSF g) is now a Gaussian with a FWHM of two pixels. The new linear pixel scale is twice smaller than the original. Right: truth image used to produce the simulated data in the left panel. The photometry of the point sources in this image is displayed in Fig. 10. The extended sources are recovered very well, although they are completely hidden by the crowded field of PSFs in the original data.
