• TESS Input Catalog (TIC): Catalog of stars created by the TESS Stellar Properties Working Group and is used to select targets to download at short cadence. The TIC is available through the MAST portal and via the API.
• Catalog Target List (CTL): Several lists of TIC stars that provide idicate the priorities for short-cadence observations from different science perspectives.  The same TIC ID may appear in more than one list.
• Merged Target List (MTL): A merged listed of CTLs plus specifiec engineering This list represents the targets that will be are observed at the 2-minute cadence.  It is created by merging the CTLs plus specific engineering targets.
  

Planet Search Products

The flux time series for each star observed in short cadence are then further detrended and searched for repeating signals consistent with a transiting planet, known as a Threshold Crossing Event transits.  The repeating signals that are identified in this way are known as Threshold Crossing Events (TCE).   The following products are produced by the TESS Science Processing Pipeline for each target star that produces a TCE.

• DV Time Series Files File (.dvt.fits): These files contain the sector-stitched, detrended and whitened light curves searched by the TESS Pipeline. All TCEs found on a star in one search are contained in the same file. 
• DV ReportsReport (.dvr.pdf): These pdf files contain plots and statistics for each TCE. For example, the reports contain plots of folded light curves and in- and out-of transit difference images.
• DV One-Page Summary (.dvs.pdf): This one page summary contains a quick overview of each TCE and much of the most important information about the TCE to determine if the signal is likely caused by a transit or shows evidence of being caused by an eclipsing binary or instrumental noise. Each TCE gets its own file, so if multiple TCEs are found on the same target star, there will be multiple pdf files.

• Threshold Crossing Events (TCE): List of ephemerides (TIC number, Period, epoch) of signals that are highly correlated with a transit train. Table of TCE signals and various metrics that measure different aspects of that signal.  For each TCE, the project provides a highly detrended light curve file and a report showing relevant plots to evaluate whether the signal is a planet. The project also provides an xml file for each star that contain all the information related to the TCEs found in that star's light curve. These signals are not vetted and include various types of false positives and instrumental false alarms. Each TCE is identified by a TIC ID, planet number and search ID.
• TESS Objects of Interest (TOI):  Table containing the list of signals that are consistent being a transiting planet. This catalog provides a disposition of either planet candidate or false positive which can change as more information is gathered about a target from follow-up and additional analysis of the data.
• Confirmed Planets :  Transiting planets found in the TESS data for which follow-up data provide a mass of the planet.  See the exoFOP-TESS page for more information about what follow-up data are available.
