Diagnostic diagram: lines are a fit through Hii regions from Baldwin et al. (1981, gray) and the theoretical upper limit for the starburst model from Kewley et al. (2001, black). The errors of the six Hii regions correspond to the size of the symbols. The gray diamonds are Hii regions from a sample of edge-on galaxies from Flores-Fajardo et al. (2009).
