Warsaw Catalogue of cometary orbits

In addition, when drawing conclusions about the origin of these objects, it is crucial to control the uncertainties of orbital elements at each stage of the dynamical evolution. I apply a completely homogeneous approach to determine the cometary orbits and their uncertainties.

The resulting catalogue is suitable for the investigation of the origin and future of near-parabolic comets. First, osculating orbits were determined on the basis of positional data. Second, the dynamical calculations were performed backwards and forwards up to 250AU from the Sun to derive original and future barycentric orbits for each comet.
