Description:
A catalog is presented of some 1200 Galactic objects which have radial
velocities and abundances [Fe/H]≤-0.6. These data have been
analyzed to yield information on the kinematic properties of the older
populations of the Galaxy and on the interdependence between
kinematics and abundance.
