摘要
This paper derives astrometric data for the Galilean satellites from 213 light curves of 86 mutual eclipses and occultations that occurred in 1990-1992. Comparisons of these data with predictions based on the most precise modern ephemeris (E5) generally show good agreement, although it is rather poorer in the case of J1 (Io).
