Source and lens trajectories for a simulated binary-source point-lens microlensing event involving Keplerian orbits. We present the unlensed sources (solid lines) and the lensed images (dashed + dotted lines). The green line is the flux-weighted average of lensed source positions, as observed on the sky. Note that mag_S,pri = 16 and mag_S,sec = 17. This event has the following Keplerian elements: ω_pri = 30°, Ω_sec = 10°, i = 90°, e = 0.6, P = 1000 days, ℵ_pri = 3 mas, and ℵ_sec = 8 mas. The Einstein radius is 2.9 mas. We simulate this event over t_E = 208.47 days. The lens (8 M_⊙) is held stationary.
