Fig. 3.
Left panel: orientation of the VLT/X-shooter slit. The white cross marks our VLBA position of GRB 111005A. Right panel: 2D spectra. The horizontal axis corresponds to the wavelengths and the vertical axis to the position along the slit. The rotation curve is clearly visible with each line. The emission to the left panel corresponds to the galaxy centre, whereas the one to the right panel is offset ∼4.5″ to the northwest and has a much harder ionising flux as it exhibits much higher [O III]/[O II] ratio.
