BPT diagrams using [N II]/Hα, [S II]/Hα and [O I]/Hα for individual spaxels compared to the values for other long GRB hosts (green dots) and star forming galaxies in the SDSS (gray grid). The spaxels are color coded by their deprojected distance from the galaxy center as shown in the color bar. The value of the GRB site (color coded by its distance) is shown as a diamond. Emission lines for the GRB sample have been obtained from the same data used in Fig. 18. We only plot spaxels with EW < −6 Å to remove diffuse interstellar gas (DIG) as explained in the text.
