## Ephemerides of the five major Uranian satellites by numerical integration
A catalogue is compiled of all available published and unpublished
Earth-based observations of the satellites of Uranus. References are
given to each of the published datasets. A brief survey of the
observations is made concentrating on the different types of data and
their quality. A numerical integration is fitted to observations in
the time interval April 1977 to October 1995, which includes some of
the best quality photographic data, the Voyager astrographic data, CCD
data and meridian circle observations. The mass values found are
expressed as the product of the universal gravitational constant times
the mass of the body, in units of . Values
determined for the mass of Uranus of 5794054
163, the dynamical flattening J
