[OIII]λ5007/Hα ratio corrected for dust attenuation. We present the logarithm of the ratio as a function of oxygen abundance computed using Curti et al. (2020) FMR relation on the x-axis. The secondary axis corresponds to the translation in terms of gas-phase metallicity where the solar values are 0.0142 or 8.76. The ratio has been corrected using the attenuation for each line as computed with CIGALE. A linear and logarithmic median and mean ratio of 0.86 (−0.065) and 0.89 (−0.047) are found. The 0.32 dispersion corresponds to the standard deviation.
