Comments.
Data are deduced from the photometric observations

Format.
1. Observatory code (see the table in the relevant article).
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. Position angle A in degrees (topocentric for mutual occultation
or heliocentric for mutual eclipse)
10. Precision of apparent position along the apparent relative trajectory
of the satellite as obtained with the least-square method, in arcseconds
11. O-C along the apparent relative trajectory, in arcseconds.
12. Flag R assigned showing the reason why only one coordinate was determined:
R=0 - there is no doubt about the results;
R=1 - the flux zero level in the photometry is not correctly excluded;
you can use the position angle as an astrometric result
instead the values $X, Y$.
R=2 - the flux drop is small and noise signal is big in the photometry,
astrometric results are doubtful.
R=3 - there is a significant error in the photometric data,
the results are not suitable.
