Table of Ultracool Fundamental Properties

The Table of Ultracool Fundamental Properties is a subset of The UltracoolSheet (version 2.0.0, in preparation) associated with Sanghi et al. (2023): The Hawaii Infrared Parallax Program. VI. The Fundamental Properties of 1000+ Ultracool Dwarfs and Planetary-mass Objects Using Optical to Mid-IR SEDs and Comparison to BT-Settl and ATMO 2020 Model Atmospheres.

It is a comprehensive compilation of the astrometric, photometric, spectroscopic, age properties, and fundamental parameters (bolometric luminosities, masses, radii, surface gravities, and effective temperatures) of all objects in the above paper's sample.

Three CSV files are provided here: (1) Ultracool_Fundamental_Properties_Table.csv (with all object information); (2) AgeValues.csv (with age values for the different age assignment categories); and (3) References.csv (with citation information). The README.txt file contains a detailed description of the contents of the three CSV files.

When using data from the Table of Ultracool Fundamental Properties, please cite the individual papers from which the data comes. Citations codes are included for all the data in the tables, and the References table translates the citation codes into ADS bibcodes, Papers citekeys, and publication titles. For research that benefits from this compilation, please cite this Zenodo post and include the following acknowledgment:
