HD 20794 d
Host HD 20794 · 4 published parameter sets in the archive snapshot. The archive default is highlighted. Each row is computed from that paper’s own values only.
Why this planet is in the demo: default 2.98 M_earth (Msini, Nari et al. 2025) vs composite 4.8 M_earth (Msin(i)/sin(i), limit flag 0, Pepe et al. 2011); ratio 1.61.

What the composite table would give
The archive’s Planetary Systems Composite Parameters table keeps one row per planet and fills each value from whichever reference its rules pick, so a single row can mix papers.
