Posterior eccentricity distributions for three planet size classes derived from hierarchical Bayesian inference. Left: single-Beta distribution fits. Right: two-component Beta mixture model fits. Colors denote sub-Neptunes (1–4 R⊕, blue), sub-Saturns (4–8 R⊕, purple), and Jovians (8–16 R⊕, orange). Solid lines show median posteriors; shaded regions indicate 68% credible intervals.
