TESS–Gaia Light Curve: A PSF-based TESS FFI Light-curve Product [PDF]
The Astronomical Journal, 2023 The Transiting Exoplanet Survey Satellite (TESS) is continuing its second extended mission after 55 sectors of observations. TESS publishes full-frame images (FFIs) at a cadence of 1800, 600, or 200 s, allowing light curves to be extracted for stars ...
