| NOTE:  Above ephemerides represent fully-perturbed, light-time-corrected solutions to data spanning 1835-1989  |                
| (cf. the EPHEM.TXT file by D. Yeomans in the DOCUMENT directory).  Ephemerides for HOUR=0.0 UT are directly    |                
| from Yeomans; values within a UT day have been generated using a 7-point interpolation scheme and Yeomans'     |                
| daily (0h UT) values.  The first and last lines in the table span the time interval between the beginning of   |                
| this data directory and the beginning of the next one.                                                         |
