Notes. The Seyferts and LINERs classification results in Fig. 11. The upper and lower part of the table describes the classification results for galaxies lying above the Ka03 and Ke01 line in the [N II] BPT diagram, respectively. Column 1 shows the different S-L lines. Column 2 shows the N_S1. Column 3 shows the N_S2. Column 4 shows the N_L1. Column 5 shows the N_L2. Column 6 shows the N_S1/N_L1. Column 7 shows the N_S2/N_L2. Column 8 shows the $P_{L_{ex}}$ $P_{L_{\mathrm {ex}}}$ , with the results in percentage form. Column 9 shows the $\frac{N_{L 1} \times N_{S 2}}{N_{S 1}}$ $\frac {N_{L1} \times N_{S2}}{N_{S1}}$ . Column 10 shows the n₁. Column 11 shows the n₂.
