TESS Exoplanet Vetter (TEV) Website

The TESS Exoplanet Vetter Website

Short for TESS Exoplanet Vetter, TEV is the source of truth for all TESS Objects of Interest as well as maintaining the TOI promotion process. This application ingests exoplanet candidates from NASA’s SPOC and MIT’s Quick-Look-Pipeline planet searches and allows users to search for particular targets as well as view PDF reports.

TESS Objects of Interest (TOIs) come from visual analysis of significant threshold crossing events by the TESS Science Office (TSO) at MIT. These events are found by the TESS SPOC pipeline of record and the TESS Science Office Quick Look Pipeline (QLP). For in-depth description of the TOI process, see Guerrero et al, 2021.

TOI Catalog

The official TOI Catalog is managed by the TSO. Objects in this catalog have been triaged, vetted, and determined to be an object suitable for follow-up observations by the TESS Follow-up Observing Program (TFOP). The TOI Catalog is a “living document” that is subject to change as new information becomes available from additional TESS data or other follow-up observations.

TOI Table Columns

TOI Table Columns

No.	Name	Notes
1	Parameter Source Pipeline	Pipeline and delivery supplying the current parameters for a target, either SPOC or QLP. For more information on delivery names, see [insert link]
2	Detection Pipeline(s)	Pipeline(s) that detected the TOI in the sector in which it was alerted. Here, "detection" is defined as a transit signal passing automated triage (TEC for SPOC signals or Astronet for QLP signals) followed by review by the TOI Vetting Team in which the signal is determined a likely planet candidate ready to alert as a TOI. Possible values: SPOC (detected by the SPOC pipeline), QLP (detected by the QLP pipeline), FAINT (detected by the QLP Faint Star Search, for further details see Kunimoto et al. 2021. ), SPOC/QLP (detected by both SPOC and QLP), SPOC/Faint (detected by both SPOC and QLP Faint Star Search), or CTOI (the TOI was the result of a community submission to ExoFOP or request for a TOI number).
3	TIC	A unique identifier for every object in the TESS Input Catalog (TIC). The ID is unique and permanent. If an object is removed from the TIC in later versions, a new object is removed from the TIC in later versions(clarify this?). A new object will never inherit an old ID.
4	Full TOI ID	TESS Object of Interest (TOI) identifier. This is assigned to each TOI at time of alert, with the whole number indicating the system TOI while the decimal number indicates a specific planet candidate. Ex. TOI 2000.01 would be the first candidate in the TOI 2000 system while TOI 2000.02 would be the second candidate and so on.
5	TOI Disposition	The current disposition for a TOI. At time of alert, TOIs have one of the following dispositions: “PC” = planet candidate, "CP" = confirmed planet (identified with TESS), or "KP" = known planet (identified prior to TESS). If a TOI is identified as a False Positive (FP) or False Alarm (FA) by TFOP, this disposition will be updated to reflect this new information. Non-planet dispositions are: "EB" = eclipsing binary, "V" = stellar variability, "IS" = instrumental noise/systematic, or "O" = other astrophysical.

TCE Catalog

As of 2025, TEV now hosts the Threshold-Crossing-Event (TCE) Catalog. The Threshold Crossing Event (TCE) catalog as managed by the TESS Science Office (TSO). This catalog contains any transiting signal detected by SPOC, QLP, or the FAINT exoplanet search pipelines.

135	All Star Files	All Star reports on the target's host star via the Atlas system.
136	Eclipsing Score	The astronet score for periodic eclipsing signals. This includes both planetary transits and non-contact eclipsing binaries. In the triage process, we do not consider information that would distinguish an eclipsing signal from background stars from an eclipsing signal on the target star. Both cases would be labeled as E if they satisfy all the other criteria.
137	Single Score	The Astronet score for events containing only a single transit or events where an incorrect period or period alias is assessed to be reported from BLS.
138	Binary Score	The Astronet score for contact eclipsing binaries. They are distinguishable from non-contact binaries through their continuous ingress/egress slope.
139	Junk Score	The Astronet score for junk. This includes other astrophysical phenomena like stellar variability as well as instrumental phenomena like scattered light (due to the Earth or the Moon approaching the field of view and reflecting light into the camera) or artifacts introduced at the times of spacecraft momentum dumps (when the spacecraft’s reaction wheels correct for the spacecraft’s speed).
140	Not Sure Score	The Astronet score for "not sure". No conclusive label decision could be made for these TCEs. Often, an N label was given when a weak signal bordered on being on E or J.
141	Human Triage	This column is a boolean flag on whether a human manually triaged this target. True values denote the object passed, while False denotes rejection. A NULL value indicates that no decision was made on the object (and was likely rejected by some metric such as SNR and stellar brightness cutoffs).
