Comparison of planetary populations. Theoretical (blue) represents planets in KOBE multi-planetary systems (KMPS) and observations (green) are the CKS multi-planetary systems (CKSM). Left: Scatter plot with planetary radius on the y-axis and period on the x-axis. The dashed line shows the maximum period of a planet that can be found by KOBE. The dotted line shows the minimum radius of a planet around a 1 R_⊙ star for producing a transit S/N of 10. The underlying theoretical population is shown in grey. Right: Comparison of radius (top)and period (bottom) distributions. The radius valley can be clearly seen in the planets found by KOBE and the California-Kepler survey.
