data included in standard data file: no
Comments.
The data file is composed from 1138 lines
Each line from 1138 given lines contents the coordinates
from one plate for 1 to 4 satellites.
Numbers of observations mentionned above present
for each satellite 0.5 of amount of the given
coordinates X and Y.
Format.
1. Year of the moment of observation
2. Month of the moment of observation
3. Day of the moment of observation
4. Hour of the moment of observation
5. Minute of the moment of observation
6. Second of the moment of observation with decimals
7. (N f) Code of the reference frame:
1 = mean terrestrial equatorial frame, 1950,
2 = Jovian equatorial frame of the date,
3 = others special frames.
8. (N c) Code of referential center:
1 = arbitrary point supposed to be the center of the plate,
origin of tangential coordinates,
2 = center of observed Jupiter.
