Merger fraction for star-forming galaxies with SFRs above indicated distances above the MS for SDSS and KiDS data (top panel) and CANDELS data (bottom panel). To avoid low number statistics, only thresholds above which there are 50, or more, galaxies are shown. The SDSS (top panel, purple), KiDS (top panel, blue), and all CANDELS data show a trend of increasing merger fraction as the distance to the MS increases, although the CANDELS-z000 drops again above 0.62 log(M_⊙ yr⁻¹).
