Comments.
Format.
1. (Code of obs) Code of observatory (see above)
2. (Ref sat) Reference satellite (eclipsing or occulting)
3. (Type of ev.) Type of mutual phenomena: o - occultation, e - eclipse
4. Subject satellite (eclipsed or occulted)
5. Year of the moment of observation
6. Day (!) of the moment of observation
7. Month of the moment of observation
8. Hour of the moment of observation
9. Minute of the moment of observation
10. Second of the moment of observation with decimals
11. (DT) Time correction, see article (correction to the midtime taken
without the phase correction), s
12. (Dx) Longitude correction to Sampson's (1921) theory, km
13. (Dz) Latitude correction to Sampson's (1921) theory, km
14. (D(R.A.)) Separation between the satellites
(subject satellite - reference satellite) in right ascension, arcsec
(geocentric for occultation, heliocentric for eclipse)
15. (D(decl.)) Separation between the satellites
(subject satellite - reference satellite) in declination, arcsec
(geocentric for occultation, heliocentric for eclipse)
16. (JED) Ephemeris time at Jupiter
17. (PH1) Orbital phase angle, degrees (geocentric for occultation,
heliocentric for eclipse)
18. (PH2) Orbital phase angle, degrees (geocentric for occultation,
heliocentric for eclipse)
19. (Weight) Weights calculated according to a formula
discussed by Aksnes and Franklin (1976)
20. (N) Note (if equal to 1) that latitude correction is not accurate
(see article, it corresponds to the apperance of Dz in parentheses
in the table in the article)
