ΔSFR as a function of merger time. The green circles show the μ from the Gaussian fitting of the mergers. The errors on these points are the standard deviation of the merger times in the merger time bin (x axis) and the error in μ from the Gaussian fitting combined with bootstrapped ΔSFR uncertainty (y axis). The colour corresponds to the number density from low (purple) to high (red). The light shaded region indicates where pre-mergers should lie and the dark shaded region indicates where post-mergers should lie. The yellow horizontal line indicates ΔSFR = 0.
