Description:
Absolute magnitudes, metallicities, effective temperatures, surface
gravities, distances, and tangential velocities are calculated for
5498 F stars with homogeneous data on uvby photometry and proper
motion, and placed within 80 pc from the Sun. Components of space
velocities, eccentricities of galactic orbits, perigalactic and
apogalactic distances, and maximal remotness from galactic plane are
presented for 1787 stars. Isochrone ages are determined for 3405
slightly evolved stars proceeding from Revised Yale isochrones.
