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.
Using the TOI Releases and TESS Data
All users of TESS data are encouraged to follow the best practices underlined in the TESS publication policy should be followed. All members of the TESS Team (Co-I, Collaborator, WG member, TESS staff) follow the TESS publication policy.
If users are creating a publication, they should include whichever of the below is most appropriate in the acknowledgements.
Publications based on data obtained from the TESS project are requested to include the acknowledgment:
“Funding for the TESS mission is provided by NASA’s Science Mission directorate.”
Once the TOI Releases are public:
“We acknowledge the use of public TOI Release data from pipelines at the TESS Science Office and at the TESS Science Processing Operations Center.”
Once the data are public on MAST:
This paper includes data collected by the TESS mission, which are publicly available from the Mikulski Archive for Space Telescopes (MAST).”
Creation of TOIs
The TOI Release comes from visual analysis of significant threshold crossing events by the TSO. These events were found by the TESS SPOC pipeline of record.
The TESS team has developed a process for community TOIs (cTOIs). These cTOIs will be from the FFIs, and not from the SPOC data products. MIT’s Quick Look Pipeline (QLP) is one source of cTOIs. See this page for more on submitting your own cTOIs.
How to Navigate the TOI Release Portal
A reference image of the TOI Release portal is shown below.
The columns include the TIC ID, the TOI ID, the Disposition (as determined by the TSO vetters), RA, Dec, TESS Magnitude, Planetary Radius, Period, Transit Duration, Transit Depth, and other relevant information about each TOI. Details on each of these columns can be found near the end of this document. Users can interactively sort on the different columns using the web interface.
