Case of a BH falling from rest on a radial orbit. a) The solid black curve graphs the angular momentum accrued over time (left-hand axis with black labels); the right-hand axis is the scale for each velocity component (red curves). b) The cylindrical radius (in black, left-hand axis) and velocity (right-hand axis, in turquoise) are shown as a function of time. The dotted line at the bottom is the z coordinate bound to ±12pc.
