Position-time trajectories of three Lagrangian points along the x-axis: q/L = 0.072, 0.087, 0.103 (left to right) in the SYM simulation. The data points (red, labeled “Vl” as in Vlasov solver used for the simulations) have been cubically interpolated. The self-similar fits, made using the least-squares method with ϵ = 0.5, are shown in blue. The time intervals (green) within which the trajectories follow the fits were computed assuming a threshold: Δr/r_data≤10%. The spatial resolution of the tessellation grid is ∼0.0005 comoving box units.
