4 Datasets of the observations

In Table 4, we give an extract from our observations made in 1996, which were differenced to form the positions of each satellite relative to Titan and are given in the form of polar coordinates, as described in the previous section. These are apparent topocentric data after differential refraction reduction, no correction has been made for the effects of stellar aberration and parallax. The times of the middle of the exposures are given in Universal Time. Table 5 gives the raw data of the measured satellites positions with the corresponding dates of observations as presented in Table 4. The full observations, which can be supplied by E-mail, are available on request (pub2@ms.sxso.ac.cn).
