Notes. The final metallicity applied for each region (bottom line of the table) was derived from the mean of the recalibrated metallicities in the bottom part of the third epoch. (*)This method chooses the optimal among given: M91, KD02 N2O2, KD02 N2Ha, KD04 R23, [N2, N2O2] diagnostics (Kewley & Ellison 2008).
