Fig. 1.
Examples of galaxy and PSF images generated from GALSIM. Top two rows: examples of galaxies with a de Vaucouleurs bulge and an exponential disc. Middle two rows: examples of galaxies with a single Sérsic profile. In these two cases, we show galaxies of a variety of sizes and in increasing order. Bottom two rows: examples of PSF images, showing a wide range of complexities from simple and isotropic to complex and anisotropic. The PSF images have been zoomed in for visual reasons.
