Binary geometries available in BAGLE. Source trajectories on the sky plane are represented in pink, and lens trajectories are represented in black. The change in R.A. is plotted on the x-axis, and the change in decl. is plotted on the y-axis. Models with binary lenses (left column), binary sources (middle column), and both binary lenses and sources (right column) are supported. Secondary companions can have fixed separation and angle relative to the primary (top row), linear motion (second row), accelerating motion (third row), or full Keplerian orbital motion (fourth row).
