Top: Schematic RV phase curve of two planets orbiting a star: a massive long-period planet and a smaller, shorter period planet. The red box covers one orbit of the short-period planet, which is depicted below after the longer period planet’s signal has been subtracted. Bottom: In a multi-planet scenario, the in-quadrature prioritization systems starts by folding on the shorter period planet’s phase curve and defining the phase bins. The blue bins are centered on the quadrature points of the selected planet’s orbit, while the white bins are centered on the zero-crossing points.
