Free-Floating Planet Candidate Full Catalogue

This release contains the full catalogue of 296 free-floating planet (FFP) candidates compiled for the Master's thesis "The Properties of Free Floating Planets", combining astrometric, photometric, spectroscopic, direct-imaging, and microlensing detections across 18 star-forming regions and young moving groups.

Candidates are classified into three reliability tiers (Robust, Probable, Tentative) based on mass estimates derived under three benchmark ages (3, 5, and 10 Myr).

This catalogue underpins the Research Note "A Census of Free-Floating Planet Candidates and the Prospects for Roman" (San Andrés Navarro, Rebollido Vázquez, & Dantas, 2026).

See the README for a full description of all columns.
