Warning
This is an older version of the TESS Input Catalog. It is only available for bulk downloads. The TIC Version 8.2 is the current version, please consult that documentation.

Info
The data release notes are updated by the TESS Stellar Parameter Working Group as issues are found.

The following table summarizies the known cases. These targets are identical and should have been matched together in TIC v8, but were not. Users should be aware that these are the same objects, and thus parameters from the TIC8 ID under the "Gaia DR2" column can be associated with the same TIC8 ID in the "from TIC7" column.

TOI	TIC8 ID (from TIC7)	TIC8 ID (from GaiaDR2)	Comments
454.01	153077621	651051509	153077621 is a cool dwarf
573.01	296780789	876200724	296780789 is a cool dwarf
722.01	38509907	684936227	38509907 has a spectroscopic Teff
1421.01	329277372	2019613336	Gaia photometry unreliable, RUWE = 41.2 (not ok)
--	430528563	2014876481	this is Tycho2 3969-00744-1
1309.01	430528566	2014876461	this is most likely Tycho2 3969-00744-2
651.01	72090501	709725833	likely TYC 5366-2280-1 (Vizier: bad RA, Dec)
1169.01	302518439	802647157 and 802647158	TYC 4381-01655-1 and -2

Additional Note: TIC 72090499 and 72090500 looked as if they should be joined, but they are two bona-fide stars with separate detections in Gaia DR2 and Tycho.

The following table contains the original TIC8 ID (from the unresolved source in TIC7) and the two TIC8 IDs for the source coming from the Gaia DR2 IDs.
