Left panel: histogram of the distance at the time of merger for the two sets of simulations of all spectral types. The results for a threshold period mass of 2 M_⊙ and 5 M_⊙ are depicted in blue and orange, respectively. The black line indicates a 100 pc distance. Percentages show the fraction of mergers that occurred within a 100 pc distance. The dashed black line highlights the cut-off distance at approximately 4.25 on the logarithmic scale. Right panel: distance histogram for B-type stars only. Colour coding corresponds to that of the left panel.
