Visualization of 1500 orbit draws from the posteriors of the b, c, d, e, and inner planet models overplotted on the combined 2021 epoch. Directly modeling the photometry in our images allows us to simultaneously detect the known planets and produce orbital posteriors that agree with previous fits to extracted astrometry.
