The five largest satellites of Uranus: Astrometric observations spread over 29 years at the Pico dos Dias Observatory
TL;DR: In this paper, the positions of the five largest satellites of Uranus from observations spread over almost three decades with photographic plates and CCDs (mainly, taken at the Pico dos Dias Observatory - Brazil) are presented.
