These orbit files should be considered as `preliminary'--final results will appear after the next batch of MPCs.
- Numbered objects
- Multi-opposition unnumbered objects
- One-opposition objects (perturbed solutions)
- One-opposition objects (unperturbed solutions)
- Complete orbital sets (subsets of the above datafiles) are available for the following classes of object:
Information on the format of the orbits is available.
