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.

EPIC 206024342 none (appears as "p4" in the paper) The entire candidate The candidate is labeled "confirmed" The candidate is not in the archive Adams et al. 2021 The fourth signal in the EPIC 206024342 system (labeled as "p4" with a 27-day orbital period) was mislabeled in one table. After private communication with the author, it was determined this object remains a planet candidate.
