| 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. |

DEFINITIONS OF LESS OBVIOUS FIELDS IN THE EPHEMERIS TABLE:
THETA = Sun-Earth-Comet angle (degrees)
BETA = Sun-Comet-Earth angle (degrees)
MOON = Angular separation of comet and moon (degrees)
PSANG = Position angle of prolonged radius vector (degrees, measured from north through east)
PSAMV = Position angle of minus orbital velocity vector (degrees, measured from north through east)
