Comments.
Data are deduced from the photometric observations
of the mutual occultations and eclipses made
during the international campaign in 2021.
The description of these astrometric data
is given in the relevant article (see Reference).
The coordinates of the observatories are given below.
The first group of the data is presented in this item.
The "O-C' are given with respect of the theory by V.Lainey
(Lainey, V., Arlot, J. E., Karatekin, O., van Hoolst, T. 2009.

Format.
1. Observatory code see the table above.
2. The type of the phenomenon (eclipse or occultation) including the
satellite numbers. The type of phenomenon is coded as n_a o n_p
or n_a e n_p for a mutual occultation or eclipse, respectively.
Here $n_a$ is the number of the occulting or eclipsing satellite
and $n_p$ is the number of the occulted or eclipsed satellite.
3. Year of observation
4. Month of observation
5. Day of observation
6. Hour of the astrometric data (UTC)
7. Minute of the astrometric data (UTC)
8. Seconde of the astrometric data with decimals (UTC)
9. X coordinate in arcseconds (topocentric for mutual occultation
or heliocentric for mutual eclipse)
10. Y coordinate in arcseconds (topocentric for mutual occultation
or heliocentric for mutual eclipse)
11. sigma of X in arcseconds
12. sigma of Y in arcseconds
13. "O-C" for X in arcseconds
14. "O-C" for Y in arcseconds
15. Angular separation s (in arcseconds) corresponding to X, Y.
16. Position angle A (in degrees) corresponding to X, Y.
17. Flag Q indicating the quality and the reliability of the result:
Q=0 - there is no doubt about the results;
Q=1 - astrometric results are doubtful.
18. The minimum level (S min) of normalized flux.
