Abstract
We present the measurements of 58 visual double stars made in 1999 and 2000 with the 50 cm refractor of the Nice Observatory and attached CCD camera, using an algorithm based on the adjustment of a tridimensional mathematical surface (Table 1). 2 new binaries discovered by Hipparcos were measured.


Key words: astrometry -- stars: binaries: visual
