SFR–M_⋆, O/H–M_⋆, and sSFR–M_⋆ relations for our sample of galaxies. Star-forming (colored crosses) and composite (gray triangles) galaxies based on the BPT classification are represented in each diagram. The left and central panels correspond to Case A and Case B, respectively. We included the linear fit of the SFR–M_⋆ relation for all the SF galaxies. The right panels correspond to Case C, with the aperture corrected. In the upper panel we include the linear fit of the SFR–M_⋆ relation for all the SF galaxies considered in Case C (dashed red line), the fit from Case A (dotted green line), and the fit from Case B (dotted blue line). In the bottom-right panel, the sSFR–M_⋆ relation, we also include a fourth relation (dotted red) that corresponds to an aperture-corrected SFR (Case C) normalized to the mass measured in the fiber spectrum (Case A). In the lower panels we show the difference between the linear fit in Case C and the linear fits of Case A (dotted green line) and Case B (dotted blue line).
