One- and two-dimensional, afterglow-subtracted X-shooter spectrum centered around the location of [O iii](λ 5007) at z = 2.3586 (i.e., observed 16 820 Å). The one-dimensional spectrum (black data) fitted by a Gaussian (black line) is plotted against the left y-axis, while the scaling of the two-dimensional spectrum is shown by the color-bar on the right side of the plot. The two-dimensional spectrum has been smoothed by a Gaussian kernel with a FWHM of 1 pixel (0.5 Å) along the dispersion x-axis, and 2 pixel (i.e., 04) along the spatial y-axis for illustration purposes. The grey-shaded area represents the spectral resolution.
