Such examples are the eclipse observations discussed by Muller (1975) and by Fiala (referred to by Rothschild, 1982), and the observation of Neptune by Galileo as discovered by Kowal and Drake (1980). THE JPL "LONG EPHEMERIS" DEI02/LE51 C. 49 Quantitative Parameter Determinations One sometimes wishes the value of an associated ephemeris parameter, averaged over a long period of time. Standish (1982) has used DEI02/LE51 in determinations of the mean obliquity and dynamical equinox. D. Integration of One-Body Orbits The integration of the orbit of an asteroid or comet, for be quickly accomplished using the pre-computed positions planets as input datL Scholl (1982) has reported a nearly an order of magni tude in computer time for such opposed to integrating the full n-body system.

M. 5), the ephemeris being integrated both forward and backward from this date. The initial conditions were the best available at that time and represented a least squares adjustment to a variety of observational data types. These included: 1) Lunar-laser ranging; 2) Mariner 9 and Viking Orbiter spacecraft ranging; 3) radar-ranging to Mercury, Venus, and Mars; and 4) Meridian circle optical data.

Thenuwe can apply to (19) the study made in section 3. , 1982). - As we have said, the solution of P{a) = 0 as well as the effective calculation of the values of a, ~, y which determines a regularizing function 9 S {r) with g5{r) > 0, seems to need numerical methods. Now we give two numerical examples, obtained through the system (12), which show the feasibility of the method proposed. The existence of g5{r) for a wide set of values for the orbital parameters a, e, I, remains to be analyzed. 65 10-6 R.
