TESS Quick-Look and Lightcurve Analysis (TEQUILA)

The TEQUILA (TESS Quick-Look and Lightcurve Analysis) project provides a comprehensive catalog of variable point sources extracted from the Transiting Exoplanet Survey Satellite (TESS) Full-Frame Images (FFIs) spanning Sectors 1–26 of the prime mission. Using a Difference Image Analysis (DIA) pipeline, TEQUILA delivers over six million differential photometry lightcurves that capture a wide range of astrophysical variability — including stellar variables, transient events, and solar system objects. Each lightcurve is provided in FITS format with metadata describing data quality, blending, systematic classification, and SSO contamination flags. The catalog serves as both a discovery resource and a foundation for statistical time-domain studies using TESS data.
