000001853 520__ $$aWe present photometric and astrometric data of about 280 visual double stars of the ``intermediate'' class, i.e. with angular separations mainly in the range 2arcsec  rho  12arcsec . The observations have been obtained in 1991-92 with a CCD camera attached to the 91 cm Dutch telescope at ESO La Silla, Chile. Differential magnitudes of the double star components as well as magnitudes and colour indices of the individual components have been determined in the Cousins V and I passbands with an internal error of about 0.005 mag and an external accuracy of less than 0.03 mag. In addition, angular separations have been secured to an internal accuracy of 0.004arcsec and position angles to about 0.05degr. Tables 1 to 4 are only available in electronic form at the CDS via ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsweb.u-strasbg.fr/Abstract.html. Based on observations collected at the European Southern Observatory, La Silla, Chile.
