Abstract:
    We present the measurements of 65 visual double stars made in 1998
    with the 50 cm refractor of the Nice Observatory (table 1). A CCD
    camera was attached to this refractor. 6 new binaries discovered by
    Hipparcos have been measured. The algorithm used for these
    measurements is based on the adjustment of a tridimensional
    mathematical surface.

Remarks: - All the pairs were observed one night only
         - All the measurements were made by the team R.Gili, G.Morlet and
           M.Salaman (GMS code)
