Structural and photometric parameters adopted for the two sets of simulated galaxies at z = 2 (left panels) and z = 3 (right panels). For each set we plot the relation between the galaxy mass and effective radii in milli-arcseconds (top panel), magnitude (middle panel), and colour (bottom panel) for the 9 template galaxies. In each panel we show the scaling relations for galaxies with 3 different Sersic index with different colours and symbols (see the legend on top of the figure).
