Distribution of GSWLC galaxies throughout the selection process. Left panel: BPT diagram for the sample of GSWLC galaxies. The separation between Seyfert and LINERS (red points), and star-forming galaxies (blue to white density plot) is represented by the green curve (Kauffmann et al. 2003), while the dashed-green line represents the limit from Kewley et al. (2001). Galaxies for which L_TIR was corrected for AGN emission (and previously removed based on the GSWLC flags) are shown for information (purple to white density plot). Right panel: SFR versus M_* for GSWLC galaxies for each selection: all GSWLC galaxies (green), selection on the quality of the fits, , and availability of GALEX measurements (red), selection on MIR measurements from which L_TIR is not contaminated by the AGN component and belonging to the MGS (orange), and the star-forming sample (blue). Visible green, red, and orange points therefore represent galaxies excluded after each step. Rectangles represent the extent in SFR and M_* after each selection.
