| Fe/H, age and distance for the F-stars of an unbiased radial velocity sample at the north Galactic pole
New limits for the normalization of stellar populations of the solarneighborhood have been suggested by Sandage and Fouts (1987). Log T(e),M(V), Fe/H abundance ratio, age A, distance and color excess arepresented for 183 stars of Sandage and Fouts' unbiased radial velocitysample located near the north Galactic pole.
| U, V, W velocity components for the old disk using radial velocities of 1295 stars in the three cardinal Galactic directions
New radial velocities are presented for 1295 stars chosen at random nearthe three cardinal Galactic directions of l = 180 deg, b = 0; l = 90deg, b = 0 deg; and b = 90 deg, giving the distribution in U, V, and W,respectively, from the radial velocities alone. The measurements weremade with the coude spectrograph of the Mount Wilson 100 in. Hookerreflector. The purpose of the program is to set limits on the densitynormalization in the solar neighborhood of the old thin disk, the oldthick disk, and the halo. Many more high-velocity stars are present inthe unbiased sample than expected from previous estimates of thenormalization. The data suggest the density ratios in the solarneighborhood to be about 90 percent, 10 percent, and about 0.5 percentfor the thin disk, thick disk, and halo populations, respectively.
