ADC_Keywords: Stars, double and multiple ; Positional data
Keywords: astrometry - binaries: visual
Description:
We present (table 1) the 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. Position angle, angular
separation and magnitude difference are given. 33 new binaries
(discovered by HIPPARCOS (HDS) or newly determined from Tycho-2
database (TDS)) discovered by Hipparcos were measured.
