Since the summer of 1979, more than 17 000 visual measures were made and have either been published or are being prepared for publication.

Couteau, using the 50- and 76-cm telescopes at Nice, obtained 984 measures and also discovered 207 pairs. Of these, 13% are closer than 0″.25, and 33% have separations smaller than 0″.5. Also at Nice, Morel made 300 measures with the 76-cm refractor and discovered 6 pairs.
