These orbital solutions are expressed in the TDB and TCB time scales. The time scale transformations TT-TDB and TCG-TCB are available in the binary or text data files. The binary and text data files provide the rectangular coordinates (x,y,z) in kilometers of the bodies with respect to the International Celestial Reference Frame (ICRF). The librations are given in radians. The time scale transformation TT-TDB and TCG-TCB is given in seconds for the files including it.
