The Hipparcos data are an important source for constraining the statistical distribution functions for the binaries in the general field. The present study uses the resolved binaries (separation 0.1-10 arcsec, magnitude-differences below 4 mag) to check directly the frequency of main-sequence binaries with (linear) separations 30-500 a.u. and mass…
