Top and middle panels: normalised total flux light curves of the emission from the 2D recoiling black hole simulation for θ_obs = 0.1° and θ_obs = 60°, respectively. Solid lines are for the simulation run with three AMR levels and a tolerance of ε_t = 0.005. Dashed lines are for the uniform grid simulation run of equivalent resolution. Bottom: flux difference between the 2D AMR and uniform run light-curves for θ_obs = 0.1° (solid) and θ_obs = 60° (dashed).
