  The Transiting Exoplanet Survey Satellite (TESS) has detected thousands of
exoplanet candidates since 2018, most of which have yet to be confirmed. A key
step in the confirmation process of these candidates is ruling out false
positives through vetting. Vetting also eases the burden on follow-up
observations, provides input for demographics studies, and facilitates training
machine learning algorithms. Here we present the TESS Triple-9 (TT9) catalog --
a uniformly-vetted catalog containing dispositions for 999 exoplanet candidates
listed on ExoFOP-TESS, known as TESS Objects of Interest (TOIs). The TT9 was
produced using the Discovery And Vetting of Exoplanets pipeline, DAVE, and
utilizing the power of citizen science as part of the Planet Patrol project.
More than 70% of the TOIs listed in the TT9 pass our diagnostic tests, and are
thus marked as true planetary candidates. We flagged 144 candidates as false
positives, and identified 146 as potential false positives. At the time of
writing, the TT9 catalog contains ~20% of the entire ExoFOP-TESS TOIs list,
demonstrates the synergy between automated tools and citizen science, and
represents the first stage of our efforts to vet all TOIs. The DAVE generated
results are publicly available on ExoFOP-TESS.
