Orbits of 451 wide visual double stars

Based on positional observations, we have determined the orbits of 130 visual double stars for the first time and improved the orbits of 321 stars. The histogram of eccentricities for all of the derived orbits corresponds to the relation f=2e. The period distribution has two pronounced maxima at P~200 and 550yr. The ephemeris relative positions and their errors have been calculated for the next three years.
