Maps colour-coded by the position of each region in the [S II] BPT diagram (blue: star formation; orange: LI(N)ER; red: AGN). The classification is performed according to the demarcation lines of Kewley et al. (2001) (to classify star-forming regions) and the AGN-LI(N)ER demarcation line of Kewley et al. (2006). The black contours correspond to EW(Hα) of 1.1 and 3 Å (same as in Fig. 4).
