Notes. Values for number ratios F_S and F_L of each S-L line. The upper (lower) part of the table describes the calculation results of F_S and F_L based on galaxies lying above the Ka03 (Ke01) line in the [N II] BPT diagram. Column 1 shows the different S-L lines. Column 2 shows the $N_{S_{t}}$ $N_{S_{t}}$ for each S-L line. Column 3 shows the $N_{S_{a}}$ $N_{S_{a}}$ for each S-L line. Column 4 shows the F_S for each S-L line, with the results in percentage form. Column 5 shows the $N_{L_{t}}$ $N_{L_{t}}$ for each S-L line. Column 6 shows the $N_{L_{b}}$ $N_{L_{b}}$ for each S-L line. Column 7 shows the F_L for each S-L line, with the results in percentage form. Column 8 shows the |F_S−F_L| for each S-L line.
