[1] Emelyanov N. V., Arlot J. E. Astrometric results phemu-1985 and phemu-1991 // Planetary and Space Science. — 2020. — Vol. 187. — P. 104946. A valuable source of astrometric data for studying the dynamics of natural satellites of planets are photometric observations of satellites during their mutual occultations and eclipses. Worldwide photometric campaigns are organized in order to observe as many events as possible. For the events that took place in 1985 and 1990–1992, the results of photometric observations of the Galilean satellites of Jupiter were published as timings of minimum light flux and values of flux drop expressed in magnitudes. These data were not suitable to refine the theory of motion of these satellites. This paper presents the results of a new reduction of the satellite astrometric coordinate differences deduced from the photometric observations of the Galilean satellites of Jupiter during their mutual occultations and eclipses in 1985 and 1990–1992. An original method of reduction that has been earlier developed by the authors was applied. This provides a significant portion of new high quality data for the general database of existing observations. The internal accuracy of obtained astrometric results is 16 mas for the observations made in 1985 and 28 mas for those made in 1990–1992. The data are included into the Natural Satellite Data Base and are available at http://nsdb.imcce.fr/obspos/bjupogae.htm. [ DOI ]
