A BPT diagram of galaxies from the ADGD using data from the NASA-Sloan Atlas (NSA) with an SNR ≥ 3 for all four BPT emission lines. Despite all objects in the catalog having strong evidence of AGN activity, only about 10.4% fall in the AGN region of the diagram (upper right), while more than one-half land in the star-forming region (bottom left).
