Galaxies simulated by our model from a catalogue with increasing axis ratios (q) and Sérsic indices (n). The magnitude and the effective radius are fixed to 24 and , respectively, for all galaxies. Each row shows galaxies with constant q, and linearly increasing n from 1 to 4. Each column shows galaxies with fixed n, and linearly increasing q from 0.1 to 0.95. The galaxies clearly show a steeper profile and are rounder from left to right and top to bottom, respectively.
