2D spectra of the host of GRB 110918A depicting four different emissions ([N ii], [O ii], Hα, Hβ). Overplotted is our Gaussian fit, where areas that overlay telluric lines are shown in white and excluded from the fit. All the values presented are raw values and do not include slit-loss or extinction corrections. Each image has been smoothed in both pixel directions for presentation purposes. a) The Balmer series transition Hα; b) the Balmer series transition Hβ; c) the forbidden transition [N ii]; d) the forbidden transition [O ii].
