Fig. 9
Near-infrared VLT/HAWK-I image overplotted with the 17 background galaxies with 51 multiply images used in Fig. 8, Sects. 6 and 8. The predicted magnifications for these galaxies are of order of few magnitudes. As an example, a magnified view of system 1 at z = 3.04 is shown, in which images 1.1 and 1.2 are magnified by 
and 
mag, respectively.
