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.
