Images obtained by color-coding the emission line regions depending on the location of the representative points in the diagnostic diagrams. Red shows high-excitation regions, green shows low-excitation regions, blue shows star-forming regions, and orange represents intermediate objects using the regions from Law et al. (2021). The images are defined where all four emission lines considered reach a 2σ level in a single spaxel. The gray lines mark the boundary of the high-ionization bicone.
