Source and lens trajectories for a simulated microlensing event with a binary lens. The solid black line is the primary lens, the solid purple line is the secondary lens, the orange point is the source position, and the solid yellow lines are the image positions. The green line is the flux-weighted average of the lensed source position, as observed on the sky. Note that mag_S = 16. The Einstein radius is 4.5 mas. We use the following orbital parameters: ω_pri = 30°, Ω_sec = 10°, i = 90°, e = 0.6, P = 1054.41 days, and an angular separation of 5 mas between the two lenses at t_com,0,⊙. We present our simulation over t_E = 412.02 days. The lenses have a mass of m_L,p =  10 M_⊙ and m_L,s =  5 M_⊙. The source is stationary.
