Comparison of Monte Carlo sampling over NS kick orientation for the case with no impact effects on the companion (blue) and with impact effects as determined from our simulations (red). Both cases show 104 samples of NS kick orientation with a uniform on distribution over the unit sphere. The magnitude of the NS kick velocity, w, is fixed at 800 km s−1 throughout. Mean values of the runaway velocities, as well as percentages of cases where the binary components remain bound and merged (and, in parentheses, merged cases that were calculated as bound). Neither bound nor merged cases appear in these distributions.
