Spectroscopic diagnostic diagrams for RGEs. The solid lines are from Kewley et al. (2006) and separate star-forming galaxies, LINER, and Seyfert; in the first panel the region between the two curves is populated by the composite galaxies. Blue dots mark the “strong” outliers (objects with a line excess with respect to the median value R [O   III]   >  5) in Fig. 1, and red dots the “weak” outliers (3  <  R [O   III]   <  5). Contours represent the iso-densities of all DR7 emission line galaxies.
