| Emission line ratio | Median slope (m’ ±σ’) | Standard deviation σstd | Slope derived by F99 correction law with Rv = 3.1 |

| [S III]λ 6312/[S III]λλ 9069,9533 | −0.696 ± 0.173 | 2.232 | −0.889 |

Notes. These median slopes, uncertainties, and standard deviations are derived from the 168 metallicity-ionization parameter bins, which have more than 1000 spaxels, and they are derived in logarithm space of line ratios. We use the 68% confidence interval of the median slope as the uncertainty (σ’) and also list out the standard deviations of the distributions of the slopes (σstd). For emission line doublets, F99 corrections use their average wavelength.
