Distribution of the different populations of SFG in their observed and derived properties, showing the magnification μ affecting each galaxy in a color-coded value (see color scale on the right). Left panel: observed Lyα flux versus apparent magnitude m₁₅₀₀, without any correction for magnification, for Samples 1 and 3. The m₁₅₀₀ value was recomputed based on the SED of each galaxy in Sample 1; for Sample 3, it is the limiting magnitude for each source as described in Sect. 4. The limiting Lyα flux assigned to all galaxies in Sample 2 is shown by a gray dashed line. Right panel: Lyman α luminosity versus absolute UV magnitude M₁₅₀₀ after correction for magnification μ. No correction for dust extinction was applied. The effect of magnification in spreading the distribution of galaxies towards the faintest values is clearly seen in this figure.
