Distribution of the ETGs of the total high-z sample in the R_e − M_⋆ plane (magenta points). Cyan triangles are a complete sample of ETGs selected from the GOODS-South field in the redshift range 1.2 <z< 1.6 (Tamburri et al. 2014) for reference. Blue(red) lines indicate lines of constant Σ(σ). We note that the sample of ETGs at ⟨ z ⟩ = 1.4 with velocity dispersions available is skewed toward more compact systems.
