- DV Time Series 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 Report (.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.

Exoplanet Result Catalogs
TESS produces several catalogs of possibly transit-like, periodic signals found in the TESS data. As the diagram above indicates, these catalogs contain overlapping populations each with different levels of signal vetting. The catalog of signals with the lowest amount of vetting are the Threshold Crossing Events (TCE) found in TCEs) which are produced by the SPOC Pipeline. Other groups may also search the short cadence time series by the SPOC pipeline (as well as signals found by searching light curves created from the TESS FFIs) are light curves, or the longer cadence FFIs for signals that may be consistent with transiting exoplanets. Since these signals have little-to-no vetting, the reliability can be quite low. Signals found in the data are then turned into TESS Objects of Interest (TOI) once the signal is vetted and determined to be sufficiently consistent with a transit or eclipse. The TOI list contains both planet candidates and false positives. The false positives are those with evidence of being an eclipsing binary. Once follow-up measurements, or additional analysis, reveal the mass of the transiting object, or remove all doubt that the signal could be caused by an eclipsing binary, the planet is considered confirmed.
