Description:
In this paper, all the light-curves obtained during the PHEMU91
campaign of observations of the mutual phenomena of the Galilean
satellites are presented. These observations give accurate astrometric
positions of major interest for dynamical studies of the motion of the
Galilean satellites. The aim of this work is to give observational
data directly usable for theoretical studies. We made 374 observations
of 111 mutual events from 56 sites. The accuracy of each observation
has been deduced from a comparison with the theoretical predictions.
For each observation, information is given about the telescope, the
receptor, the site and the observational conditions. Other data as
well as the data of the lightcurves themselves are available on the
server: ftp://ftp.bdl.fr/pub/NSDC/jupiter/pheno_mut/1991
