THREE-DIMENSIONAL MOTION OF DWARF STARS AND RR LYRAE VARIABLES.

A collection of 220 high-velocity dwarfs, 532 low-velocity dwarfs, and 114 RR Lyrae variables is given in tables with calculations of kinematical quantities in a three-dimensional model of galactic space. A metal indicator, Delta-S, for RR Lyrae variables is transformed into the ultraviolet excess, delta (0.6), which is utilized for a statistical study of kinematics under the same metallicity classification. It is found that the primordial Galaxy contracted by a factor of at least 20 in the radial direction as compared to at least 50 in the Z direction.
