Gaia DR3 IDs for TESS Input Catalog Targets
arXiv:2603.28850
Abstract
The TESS Input Catalog (TIC) was built on Gaia Data Release 2 (DR2). To date, there has not been an update to the TIC to incorporate Gaia Data Release 3 (DR3) IDs. In this Research Note, we outline how we cross-matched the TIC with Gaia DR3 IDs, its immediate applications to exoplanet research, and lessons learned when dealing with such large data sets. A full TIC/Gaia DR3 cross-match table is available for download on the Exoplanet Follow-up Observing Program (ExoFOP) website, and a Jupyter Notebook with instructions to reproduce the table is available on GitHub.
4 pages, 1 table. Accepted for publication in RNAAS. Table 1 has been integrated into the NASA Exoplanet Archive and the ExoFOP and is available for full download at https://exofop.ipac.caltech.edu/tess/gaiadr3_tic_crossmatch.php . Code to reproduce Table 1 is available on Github at https://github.com/kevinkhu/ticgaia
