10 APASS APASS stars do not have an identifier, only coordinates. We use the primary key of an internal TESS version of the APASS database table as a proxy identifier.
16 Posflag Flag to denote the source of a given TIC object’s position.
hip - stellar source is hipparcos
cooldwarfs - stellar source is the cool dwarf list
2mass - stellar source is 2MASS
lepine - Lepines All-sky Catalog of Bright M Dwarfs (2011)
tmgaia - stellar source from Gaia with unique 2MASS match
tmmgaia - stellar source from Gaia without unique 2MASS match
hotsubdwarf - stellar source is the hot subdwarf list
gicycle1 - stellar source is the GI cycle 1 program
2MASSEXT - extended source from 2MASS extended source catalog
17 pmRA The right ascension proper motions, in order of preference, are: (1) Gaia-TGAS, (2) Superblink, (3) Tycho-2, (4) Hipparcos. (5-7) Stars only found to have proper motions in UCAC4, UCAC-5 or HSOY were subject to a new set of requirements. Total UCAC-4 proper motion > 1800 mas/yr; total UCAC-5 proper motions > 200 mas/yr and < 1800 mas/yr; total HSOY proper motion < 200 mas/yr. If a star did not have a proper motion in these catalogs, it is not provided.
