  The Transiting Exoplanet Survey Satellite (TESS) is continuing its second
extended mission after 55 sectors of observations. TESS publishes full-frame
images (FFI) at a cadence of 1800, 600, or 200 seconds, allowing light curves
to be extracted for stars beyond a limited number of pre-selected stars.
Simulations show that thousands of exoplanets, eclipsing binaries, variable
stars, and other astrophysical transients can be found in these FFI light
curves. To obtain high-precision light curves, we forward model the FFI with
the effective point spread function to remove contamination from nearby stars.
We adopt star positions and magnitudes from Gaia DR3 as priors. The resulting
light curves, called TESS-Gaia Light Curves (TGLC), show a photometric
precision closely tracking the pre-launch prediction of the noise level. TGLC's
photometric precision reaches <~2% at 16th TESS magnitude even in crowded
fields. We publish TGLC Aperture and PSF light curves for stars down to 16th
TESS magnitude through the Mikulski Archive for Space Telescopes (MAST) for all
available sectors and will continue to deliver future light curves via DOI:
10.17909/610m-9474. The open-source package tglc is publicly available to
enable any user to produce customized light curves.
