Mean quasar spectral energy distribution adopted for the simulation displayed at redshift 0.4 (red) and 1.2 (green), superposed with the GALEX bandpasses (black dotted lines). It is composed of three parts, (i) the composite spectrum of Vanden Berk et al. (2001) above 1190 Å rest frame, (ii) a power law continuum below 1000 Å rest frame with an index αν to be varied in the simulation. It is shown here with values −1.4 (solid lines αλ = −0.6) and −2.4 (dashed lines αλ = 0.4), (iii) a power law continuum with an index −1.4 (αλ = −0.6) between 1000 Å and 1190 Å (rest frame).
