tess tic id
The priority is based on the relative ability of TESS to detect small planetary transits, and is calculated using the radius of the star, the contamination ratio, and the total expected photometric precision. (1) Gaia-TGAS, and (2) Hipparcos. The priority is normalized by the priority for a star with = 12.654 sectors, epsilon = 0 contamination and sigma = 61.75 ppm.a.
The artifacts are stars from an earlier version of Superblink which do not occur in any later version of Superblink.The 329 Hipparcos stars which are not in the CTL, have been propagated to epoch 2000.0, but have not been rematched.
If an object is removed from the TIC in later versions, a new object will never inherit an old ID.This column denotes the date YYYYMMDD, in which the TIC was finalized and prepared for delivery.The values given are the 64-bit "objID" values, not the IAU-format "SDSS Gaia IDs in TIC-6 are included for stars which are found in the Gaia-provided Gaia-2MASS look-up table. We expect to address these issues in a future version of the TIC. Similarly, SPflag = ‘spect’ has been replaced with ‘spec.’Stars in TICv6 which had luminosity errors larger than the luminosity value, now show luminosity errors equal to the luminosity value.A unique identifier for every object in the TIC.
In general the dwarf relations are strictly valid between specific color ranges and tend to be less accurate for very blue stars (J-Ks < -0.1) or very red stars (J-Ks > 1).
For stars having been Gaia DR1 multiples in TICv6 (POSFlag tmmgaia) we reverted to the 2MASS coordinates of the main component, and propagated the epoch given in 2MASS to 2000.0. Except where and if noted, the Data Alerts files are produced by the TESS mission pipeline. Where Msun is the mass of the Sun, G is the gravitational constant, Rsun is the Radius of the Sun, M is the mass of the star (column 73) and R is the radius of the star (column 71).
Some values are negative because of the way the parallaxes were measured in TGAS and Hipparcos.Johnson B magnitude. These do not have 2-minute cadence products at the time they were announced, and are identifed as such with "FFI" and "FFI-QLP" in the table below. APASS stars do not have an identifier, only coordinates. Specific details of the method of production and the contents of this TIC will be described in the full TICv7 Documentation can currently be found on the arXiv at (The design is the same as TICv6, in that the columns and their format are the same, but there have been additional changes compared to previous versions of the TIC. Some stars may have unphysical log(g) values, such as log(g) > 4.8. The SPOCS and GALAH catalogs do not provide uncertainties for metallicities; 0.10 and 0.05 dex were assigned, respectively, based on the reported statistical error from these catalogs.The stellar radii were estimated using a variety of techniques, in the following order of preference: (1) radii provided by the specially curated Cool Dwarf list or the Hot Subdwarf list; (2) using the Gaia parallax and bolometric corrections; (3) spectroscopic relations from Torres et al. If this is set, LumClass = DWARF, or otherwise GIANT. Flux contamination is calculated for all stars in the CTL.
New objects added to the TIC will receive new IDs. It was re-observed by TESS with 2-min cadence data in Sectors 14 and 15. Stars in the known planet list which did not have a radius, had their priority values set to 0.Stars which were included in CTL7.01, but removed in CTL7.02 - see item 2 and 3 in Section ‘Updates to the TICv7 CTL’, still have stellar parameters in TICv7.
The release notes describing these products can be downloaded via the Data Release Notes link at the top of this page.
For TIC stars with more than one associated Gaia magnitude, the ID of the brightest matching Gaia source is provided. Extended objects were treated as if they were dwarfs.
This delivery contains major changes in computed quantities compared to TICv6.
If a star did not have a proper motion in these catalogs, it is not provided.The right ascension proper motion errors are taken directly from the given proper motion catalog except in the case of SuperBlink, which in its delivered state, does not provide proper motion errors. The error in the luminosity currently only reflects the effect of the radius error but should also include the effects of temperature.In some cases the density error is larger than the density itself, these errors should be interpreted as equal to the density.Due to the preference of proper motion catalogs which are based on PPMXL, there is structure in the distribution of high priority candidates mainly above declinations larger than -30 deg.

We now calculate a Johnson V magnitude from a G-Ks color for stars which do not have a reliable observed Johnson V magnitude.Gaia magnitudes are now included for all stars with such values in Gaia This column is never NULL. Export to Word (5-7) Stars only found to have proper motions in UCAC4, UCAC-5 or HSOY were subject to a new set of requirements.

These objects should be removed in future versions of the TIC.Some stars in the cool dwarf list and the known planet host list have effective temperature which are null, but still have calculated stellar parameters. Stars in the specially curated cool dwarf list were updated, and their stellar parameters have changed. Note: Some TOI's were identified from the Full Frame Images using an MIT "Quick Look Pipeline" (QLP). As an example, here are the full file names for the data products from TIC 52368076, from Sector 1, for the second planet candidate: Using Advanced Search To Filter Down To 10 4-10 5 Targets Writing SQL Queries To Select > 10 5 Targets Can also query MAST to obtain detector pixel coordinates for a star by TIC ID only (must be online for this option).
