Predictions, based on our generative model, of the properties of planets in systems that harbour one planet similar to TOI-469 b. Upper-left: 2D histogram in the log semi-major axis versus the log mass. The positions of planets c and d are indicated with a red cross, whereas the position of TOI-469 b is indicated by a white cross. Upper-right and lower-left: distribution of the log semi-major axis and the log mass, respectively. The positions of planets c and d are indicated by the red lines with a 10% uncertainty (light red region). Lower-right: distribution of the number of observable planets with K ≥ 0.15 m/s.
