NAROO: a New Astrometric Reduction of Old Observations
Jean-Eudes Arlot, Vincent Robert, Valéry Lainey, Josselin Desmars, Anne-Charlotte PerlbargAbstract
During about one century, small telescopes participate to the astronomical observations using photographic plates. The reduction of these data was made using old star catalogues. The arrival of the Gaia reference star catalogue makes possible a new reduction of these old observations allowing to “observe in the past” with today accuracy. We will present the status of this project.
