Fig. 5

Comparison of the oxygen abundances derived using the different indicators described in the text: (i) S23 vs. O3N2 (top left panel); (ii) S3O3 vs. O3N2 (top right panel); (iii) ArO3 vs. O3N2 (bottom left panel); and (iv) ArO3 vs. S3O3 (bottom right panel). Each blue solid circle corresponds to an individual H ii region in the sample. The error bars represent half of the estimated error considering the propagation of the emission line errors and the uncertainty in the calibrator. The dashed line in each panel corresponds to the one-to-one relation.
