Total merger fraction as a function of redshift for SDSS (dark blue circle), KiDS (light blue circle), and CANDELS (red circles) by redshift bin. Also plotted are the mass limited merger fractions with log(M⋆/M⊙) > 10.0 from Conselice et al. (2003, green stars), Cotini et al. (2013, lilac diamonds), Lotz et al. (2011) magnitude limited merger fractions with MB > −19.2 (orange crosses), and the Duncan et al. (2019) lower mass (9.7 < log(M⋆/M⊙< 10.3, L, purple left triangles) and higher mass (log(M⋆/M⊙ > 10.3, H, brown right triangles) merger fractions. The SDSS data are slightly higher than would be expected and the KiDS and CANDELS merger fractions are approximately a factor of two higher than the other results.
