Abstract:
We present the measurements of 49 visual double stars made in 1997
with the 50 cm refractor of the Nice Observatory (Table 1). A CCD
camera was attached to this refractor. Some new binaries discovered by
Hipparcos have been measured. The algorithm used for these
measurements is based on the adjustment of a tridimensional
mathematical surface.
