The TESS mission has several data products ranging from the TESS input catalog to a catalog of planet candidates. Here we give an overview of what information is in each data product, how it is produced and how the data is formatted.
TESS obtains time-series photometry at two different cadences with a baseline ranging from 3 weeks out to a year. An overview of the primary science The basic observations of the sky from TESS are time series data. An overview of these data products are shown above. The entire set of CCDs for each TESS sector are downloaded every 30-minutes, these are known as the Full Frame Images (FFIs). Certain small Selected sections of sky are also downloaded at a 2-minute cadence, known as the short cadence data. The pixel-level short cadence is turned into pixel time series are stored as target pixel files and aperture photometry is performed to create a flux time series (also known as a which are stored in light curve )files. Those flux time series are then searched for signals consistent with a transiting planet, known as a Threshold Crossing Event (TCE). The TCEs, as well as signals found by searching the FFIs, are turned into TESS Objects of Interest (TOIs) when the data is sufficiently consistent with a transit.
