The BPT diagnostic diagrams from the emission line ratios measured along the minor axis of IC 5181. The radial bins are the same as in Fig. 5. The larger squares mark the values measured in the central radial bin. The solid line connects the measurements from the central to the outermost radial bin. The dotted lines separate the regions occupied by starbursts and AGN/Liners and are taken from Kewley et al. (2001).
