Variation of the observed [OIII] emission line profile as a function of the SF and AGN contribution for galaxies located in different SFR bins. In the left, middle, and right panels we show the galaxy bins located above (SUPMS), inside (MS) and below (SUBMS) the MS, respectively, with ΔSFR = 0.4, 0.0 and − 0.4 dex. The galaxy bins shown have M_⋆ = 10^10.5M_⊙. The [OIII] emission line appears at any M_⋆ and SFR.
