VLT/X-shooter spectrum of the GRB 120119A in velocity space, centred on the ground-state of the C Iλλ 1560,1656 absorption lines at z = 1.7291. The black solid line shows the spectrum and the associated error is shown in blue. The spectrum has been binned by a factor of two. The ground-state and fine-structure lines of the C Iλλ 1560,1656 transitions are marked above each of the absorption profiles. The profiles have been integrated over the velocity range indicated by the dashed red lines from ν1 to ν2 to measure the equivalent widths. C I is detected above the completeness limit in this system.
