Section of the 2D and 1D X-shooter-UVB spectra, not previously published, showing the Lyα emission line from the host galaxy of GRB 100424A (top), GRB 081121 (middle) and GRB 081222 (bottom). The lines are plotted in velocity frame centered at the systemic redshift of the galaxy (except for GRB 081222, centered on the redshift determined from the GRB afterglow absorption lines, as no other emission lines are detected). The flux density F_λ is in units of 10⁻¹⁷ erg s⁻¹ cm⁻² Å⁻¹.
