Gini vs. M₂₀ for KiDS-GAMA GZ galaxies binned by Gini and M₂₀. The average merger_neither_frac from GZ within each bin is shown from low (red) to high (blue). The green line is the Lotz et al. (2004) split between merging and non-merging galaxies while the yellow line is the Lotz et al. (2008) split. Regions with low merger_neither_frac are visually identified as merging galaxies. Panel b includes the visually confirmed mergers from Darg et al. (2010a,b) as purple stars.
