Abstract:
We present the results of a photometric and spectroscopic study of
stars in four fields toward the inner disk and Galactic bulge. The
fields are located symmetrically about the minor axis of the Milky Way
at (l, b)=(-24.8°, -6.0°), (-8.7°, -6.0°),
(+8.4°, -6.0°), and (+24.4°, -6.1°). We measured
radial velocities and strengths of selected absorption-line indexes
and derived the average reddening to each field, individual
metallicities and photometric parallaxes for each star, and mean
azimuthal rotation velocities and velocity dispersions for each field.
