Notes. We used the parameters from solution 1 to initiate the simulations in REBOUND. Beust et al. (2024) found that these solutions yield equivalent simulation results. Note: our dynamical simulation uses a different reference frame than the sky coordinate system in which these orbital elements are defined, as we define the disc plane to be at an inclination of 0°, so the planets are initialised at inclinations of 90° − ib,c.
