[N II] BPT diagrams of (a) NGC 7733 and (b) NGC 7734. The Δα and Δδ are right ascension and declination with respect to the central position of the source, which is indicated in Table 1. The solid curve in the BPT diagrams is taken from Kauffmann et al. (2003), and the region below this line shows the ionization due to star-forming regions. The dashed curve is taken from Kewley et al. (2001), and the region above this line shows the ionization due to AGN. The dashed-dotted line is taken from Schawinski et al. (2007), which divides the LINER and Seyfert AGN. The bins with an amplitude-to-noise ratio (A/N) of less than 4 in any of the lines are shown in gray.
