TEPCat: catalogue of the physical properties of transiting planetary systems

TEPCat is a catalogue of the physical properties of the known transiting extrasolar planet and brown dwarf systems. All parts of the catalogue are available as HTML tables, with and without errorbars, and machine-readable ASCII and CSV files for detailed analysis. Most of the numbers are a careful compilation of literature results, and the remainder come from my Homogeneous Studies of Transiting Extrasolar Planets papers.

Using TEPCat. The catalogue and all its contents are freely available. If you use TEPCat whilst preparing a scientific publication then please reference the description paper for the catalogue (Southworth J., 2026, arXiv:2602.23102). If this is not possible, please mention TEPCat in the acknowledgements. If you make extensive use of TEPCat, I would really appreciate co-authorship of the paper.
