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.
Part 1 is a critical compilation of the physical properties of the known transiting planets. I include results from refereed journal papers and from the arXiv preprint server. Results from my Homogeneous studies papers are given where appropriate.
The known transiting planets are split into two groups: well-studied and little-studied. The little-studied planets are those which have been analysed together in bulk rather than individually in detail. This category currently includes only Kepler planets analysed using the transit-timing variation method and without multiple radial-velocity measurements.
Part 2 is a summation of the results of my series of papers on the Homogeneous studies of transiting extrasolar planets. I include results from photometric and spectroscopic analysis (the first table), as well as final physical properties for each object (the second table). Separate statistical and systematic errorbars are given for those quantities which are calculated using theoretical stellar models.
Part 3: is for planning observations. I provide a table of basic observable quantities of transiting planetary systems which are useful for planning follow-up observations: sky position, V-band apparent magnitude, transit depth and duration, and the most recent orbital ephemerides. The known transiting planets are again split into two groups: well-studied (TEP and BD) and little-studied (KTEP).
Part 4: is a catalogue of measurements of the orbital obliquities of transiting planetary systems. Usually only the sky-projected orbital obliquity is observed. These quantities are useful in understanding the formation and dynamical evolution of planetary systems.
