Nebular metallicity correction factor p₅₀₀₇ as a function of metallicity for the relations given by Jacoby (1989), Dopita et al. (1992), and Schönberner et al. (2010), as well as for having no metallicity dependence. The relations are set up to reach a value of p₅₀₀₇ = 1 at the base metallicity Z_base = 0.007.
