Architecture of the three population samples of all multis studied in this paper. The left panel represents super-Earths, the middle panel represents sub-Neptunes, and the right panel represents mixed systems containing both super-Earths and sub-Neptunes within the same system. The point colors and styles are the same as those in Fig. 1. Each row represents a system, ordered from top to bottom by decreasing stellar mass. A trend can be observed: As stellar mass increases from low to high, the semimajor axis shifts from smaller to larger values.
