System 24 in simulation 5d (using lower planet masses of 4 M_Jup for planet e and 6 M_Jup for planets b, c, and d). Black dots are our output data points assuming the inclination and position angle of 26° and 64° from Matthews et al. (2014). The coloured dots are the observations of the HR 8799 planetary system. The system matches the data and does not experience any close encounter during our 100 Myr integration time.
