Qualitative representation of the combination of the zELDA parameters that best fit the Lyα emission of the AzTEC-3+LBG-3 system (left panel) and of the LBG-1 region (right panel). The size of the dots in the cartoon is proportional to V_exp and the color scale corresponds to the N HI value in a way that fainter color indicates lower N HI. The smallest and darkest dots show V_exp < 30 km s⁻¹ and N HI ∼ 10²¹ atoms cm⁻². The largest dot corresponds to V_exp up to 800 km s⁻¹, the faintest color to N HI ∼ 10¹⁹ atoms cm⁻².
