Discrepancies Between Literature and Archive Values

Occasionally, planet parameters in the archive are different from those in the published literature. These discrepancies are identified by the comments from the scientific community, and are confirmed by the authors. We track these errors in the table below, which is updated periodically.

The Targets Excluded from the Archive page also lists targets the archive has removed or disregarded.
