All Tables

Table 1: Date and number of CCD observations and observed hours per night. The two last columns are the mean distance (in arcseconds) of the satellites from Mars.
Table 2: Excerpt from the observations list, available only in electronic form at the CDS. From left to right: the name of satellites; the time in Julian Date (UTC); and the right ascension and declination coordinates, given in degree and fraction. These topocentric observed positions of two satellites refer to a mean equator and equinox J2000 system.
Table 3: Observed minus calculated statistics for four major Uranus satellites in 1995 and Pluto observations in 2003. For Uranus satellites reductions, we have $\overline {({\rm O{-}C})}_x$ , $\overline {({\rm O{-}C})}_y$ and $(\sigma _x)$ , $(\sigma _y)$ that are the means and the standard deviations for the residuals referred to Oberon satellite. The results $\overline {({\rm O{-}C})}_\alpha$ , $\overline {({\rm O{-}C})}_\delta$ and $(\sigma _{\alpha })$ , $(\sigma _{\delta })$ are for Pluto residuals topocentric coordinates (the units are arcseconds). $\overline {N}_{\rm obs}$ is the mean number of observations, and $\overline {N}_{\rm stars}$ the mean number of reference stars used in the astrometric calibration of Uranus and Pluto's system.
