We have calculated the root-mean-square residuals of the observations in the form of inter-satellite and measures. The orbital models are those of Harper & Taylor (1993, 1994). In Table 10 we present the statistics for Tethys, Dione, Rhea and Titan. The rejection level was and this table is directly comparable with Table 3b in Harper & Taylor (1994). For comparison, we give the same statistics for the top five datasets listed in that paper.

of Tethys, Dione, Rhea and Titan. Type code ``C 1'' denotes
and measures from CCD images.
is the number of observations included in the solution. is the total number of
observations in the dataset. is the mean residual and is the standard deviation
about the mean. See Strugnell & Taylor (1990)
