Abstract:
The Transiting Exoplanet Survey Satellite (TESS) mission has provided
the community with high-precision times series photometry for ∼2.8
million stars across the entire sky via the Full Frame Image (FFI)
light curves produced by the TESS Science Processing Operations Centre
(SPOC). This set of light curves is an extremely valuable resource for
the discovery of transiting exoplanets and other stellar science.
However, due to the sample selection, this set of light curves does
not constitute a magnitude limited sample. In order to understand the
effects of this sample selection, we use Gaia DR2 and DR3 to study the
properties of the stars in the TESS-SPOC FFI light curve set, with the
aim of providing vital context for further research using the sample.
We report on the properties of the TESS-SPOC FFI Targets in Sectors
1-55 (covering Cycles 1-4). We cross-match the TESS-SPOC FFI Targets
with the Gaia DR2 and DR3 catalogues of all targets brighter than Gaia
magnitude 14 to understand the effects of sample selection on the
overall stellar properties. This includes Gaia magnitude, parallax,
radius, temperature, non-single star flags, luminosity, radial
velocity and stellar surface gravity. In total, there are ∼16.7
million Gaia targets brighter than G=14, which when cross-matched with
the TESS-SPOC FFI Targets leaves ∼2.75 million. We investigate the
binarity of each TESS-SPOC FFI Target and calculate the radius
detection limit from two detected TESS transits which could be
detected around each target. Finally, we create a comprehensive main
sequence TESS-SPOC FFI Target sample which can be utilised in future
studies.
Description:
This catalogue is based off all TESS-SPOC FFI targets in sectors 1-55
cross-matched with gaia DR2 and DR3. In total we have 30 available
columns for each target including TIC ID, Gaia source ids and stellar
properties. Amongst these we include the estimated detectable two
transit radius detection limit for each target as the last column.
