The sample includes only galaxies with a counterpart in the infrared and log<SUB>10</SUB>(M<SUB>*</SUB>/M<SUB>⊙</SUB>) > 9, over the redshift interval 0.3 ≲ z ≲ 1.5. Our methodology consists in the comparison of the star formation rates inferred from [O II] and Hα emission lines with a robust quantification of the total star-forming activity (SFR <SUB>TOT</SUB>) that is independently estimated based on both infrared and ultraviolet (UV) luminosities. We obtain $f\, =\, E(B-V)_{\mathrm{stellar}}$/E(B - V)<SUB>nebular</SUB> = 0.69$^{0.71}_{0.69}$ and 0.55$^{0.56}_{0.53}$ for [O II] and Hα, respectively. Our resulting f-factors display a significant positive correlation with the UV attenuation and shallower or not-significant trends with the stellar mass, the SFR<SUB>TOT</SUB>, the distance to the main sequence, and the redshift. Finally, our results favour an average nebular attenuation curve similar in shape to the typical dust curve of local starbursts.STAMPAenArticle10.1093/mnras/stab35582-s2.0-85126354710http://arxiv.org/abs/2112.01885v1https://academic.oup.com/mnras/article/510/2/2061/64592222022MNRAS.510.2061RFIS/05 - ASTRONOMIA E ASTROFISICA
