Truncated orbit (solid red line), and two non-periodic trajectories (dashed blue and dash-dotted green lines) in the restricted three-body problem calculated for a binary with q = 0.15, shown in spatial (left) and velocity coordinates over the Hα Doppler map from the 2005 observations in quiescence (right). The Doppler map is shown on a linear scale. The dotted red line on the map represents circular Keplerian velocities at r_max.
