ExoCat is a catalogue of orbital parameters for known exoplanetary systems, all derived in a Bayesian framework. The advantage of this approach is that the data are all treated in a uniform manner, leading to a much-improved understanding of the final uncertainties on the parameters compared with other catalogues, which in general collate published values obtained using a variety of analysis techniques on data obtained by different observational methods. Hence the orbital parameters from this study can be used to make much more reliable inferences on the statistical distributions of orbital parameters, informing studies in fundamental areas of exoplanetary research e.g. planetary formation and evolution scenarios. 

The actual catalogue tables can be found below, in computer-readable format. For further details, including complete descriptions of the column entries, please see M.D.J. Hollis et al. (2012).
