The TESS Science Office (TSO) releases TOIs as a service to the community. The goal is to enable follow-up science prior to official data release for each sector. TOI Releases are a “living list” that is subject to change as new information becomes available. All TOI Releases are also made publicly available at ExoFOP-TESS. The TOI Releases from the official TESS pipeline (SPOC) are also available along with their data products at MAST. For more details see this page.
Note: As observers begin to follow up TOIs, some will be classified as false positives on ExoFOP-TESS.
