Deep R-band image of NGC 3934 (left) compared on the same scale with isodensity contours (right) from our simulation (see text). The simulated image includes twenty-six no-equispaced levels to emphasize the shells: seven equispaced levels from 7 × 10-5 to 1 × 10-4, eighteen equispaced levels from 1.5 × 10-4 to 1 × 10-3 and then the last level, 2 × 10-3 normalized to the total counts in the map. Black contours in the right panel correspond to star clusters 0.05 Gyr old or younger.
