We present 176 measurements of 167 visual double stars, made in 2000 and 2001 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). Position angle, angular separation and magnitude difference are given. 33 new binaries (HDS and TDS) discovered by Hipparcos were measured.
Key words: astrometry / stars: binaries: visual
