Comparison of fundamental relations as obtained for EELGs (blue) and normal SF galaxies (green). The top row displays the correlations between mean stellar age (luminosity-weighted at the left-hand side and mass-weighted at the right-hand-side) and stellar surface density. The middle row contains, at the left-hand side, the relation between present day stellar mass and the logarithm of the sSFR and at the right-hand side, stellar surface density versus the logarithm of the sSFR. The left-hand side (right-hand side) of the bottom row displays the relations between the luminosity-weighted (mass-weighted) mean stellar age and the logarithm of the sSFR. The legends display the values of the slopes after performing linear fits to the respective data points and respective standard deviations.
