Table 1: The main information about the observations for each night and each irregular satellite. In the sequence we have: the number of the frames (Fr.), the mean exposure time in seconds (Ex.), and the number of reference stars (St.) used in the astrometric calibration of the frames. The CCD type is given in the last column: type I with an array of the 770 $\times$ 1152 square pixels, corresponding to 22.5 $\mu$ m, and type II with an array of the 1024 $\times$ 1024 square pixels, corresponding to 24 $\mu$ m.
Table 2: Sample of the list of observations available only in electronic form. Starting from Col. 1 we have: the international code adopted for Jupiter's satellites; the time in year, month, and decimals of the day in Universal Time; and the coordinates' right ascension and declination, given in degree and fraction. These topocentric observed positions of eight satellites refer to a mean equator and equinox J2000 system.
Table 3: Observed minus calculated statistics for all observations of each satellite. The units are arcseconds and $\overline {\alpha }$ , $\sigma _{\overline {\alpha }}$ , $\overline {\delta }$ , $\sigma _{\overline {\delta }}$ are the means and the standard deviations for the residuals in right ascension and declination. ${N}_{\rm obs}$ is the final number of observations for each satellite. $\sigma _{\alpha ^*}$ and $\sigma _{\delta ^*}$ is the standard deviation of the stars' reference residuals. Those two columns give the means of the standard deviations, in arcseconds, over all observed nights for the each satellite. In the last column, $\overline {N}_{\rm stars}$ , we have the mean number of reference stars used in the astrometric calibration.
