Merger fraction f_m as a function of the odds selection for i ≤ 22.5 galaxies at 0.3 ≤ z< 0.9. The filled triangles, circles, and squares are for , and 50 h^-1 kpc close pairs, respectively. The open triangles are the observed merger fractions for kpc to illustrate the selection correction from Eq. (21). In several cases, the error bars are smaller than the points. The dotted, dashed, and solid lines mark the average f_m at for , and 50 h^-1 kpc close pairs, respectively. A colour version of this plot is available in the electronic edition.
