Wide binaries in a hipparcos sample centered aroundb=0°,l=300°

Summary

3′×3′ pictures centered onHipparcos Input Catalog Objects (L3-2 INCA) have been produced in Leiden from measuring 87 plates of the Dutch glass copy of the ESO Quick Blue Survey by use of astroscan. We extract from this material our studied sample, consisting of 19825 regions around INCA objects brighter than 11 mag and outside open clusters. It enables to study in a statistical way wide binaries with apparent angular separations between 0′.1 and 1′.5 and with components within 3 mag (in the blue spectral region) of the pointed object. We present in this paper our first results on the observed characteristics of this population.
