Best-fitted parameters for the two functional forms adopted to characterize the MZR and its scatter for the different estimations of the oxygen abundance analysed here. For each different calibrator, the following is listed (i) the standard deviation of the original set of oxygen abundance values (σ_log(O/H)); (ii) the fitted parameters a and b in equation (1) to the MZR; (iii) the standard deviation (σ_MZR) of the residuals after subtracting the best-fitted curve from the oxygen abundances; and (iv) the coefficients of the polynomial function adopted in equation (2), defined as the pMZR relation, together with the σ_pMZR, the standard deviation of the residuals once subtracted the best polynomial function. The third decimal in the parameters is included to highlight any difference, despite the fact that we do not consider that any value beyond the 2nd decimal could be significant.
