• Threshold Crossing Events (TCE): 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. 

Quality Flags

The TESS pipeline populates a series of quality flags to indicate when a cadence may have been taken during an anomalous event.  These flags are available in the light curve files, the target pixel files and a subset are available for the FFIs (via a logical AND across the short cadences). The following table describes the meaning of each flag.

Engineering Files

• Collateral Pixel Files (*-{lvcol, smrow, tvcol, vrow}-*col.fits)
• Models (Huffman tables, Mean Black table, flat-field, read-noise, linearity, gain, etc.)
