Same as Fig. 2 but assuming eq. A.1 for the choice of b_max. The plot shows the outcome of the three-body simulations (upper panel) and the formation channel of the BBH mergers (lower panel) for the main NSC set initialised with eq. 12 (dark red, fiducial model) and the smaller NSC sets initialised with eq. A.1 assuming k = 1 (orange), 2 (yellow), 3 (light green), 4 (dark green), and 5 (blue).
