HD 142 b
Host HD 142 · 5 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 396.96768034 M_earth (Msini, Feng et al. 2022) vs composite 2256.5816897 M_earth (Mass, limit flag 0, Gaia Collaboration et al. 2023); ratio 5.68.

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.
