Snapshots of CCD fields in a study of the vertical distribution of stars

Snapshots of eight SA and standard fields from low to high galactic latitudes were made using the KPNO 0.9 m 2k x 2k CCD with a limiting magnitude from 19 to 22.5. The purpose of this study is to determine the vertical distribution of stars with respect to galactic latitude and z-distance in comparison with the model simulation between intermediate population to the "thick disk" component of scale height of a few kpc. Comparison of the preliminary results between observed and model simulation for three of the eight fields shows good agreement both in V-mag and B-V color distributions. A bimodal distribution in B-V at high galactic latitude seems to be represented by a halo and "thick disk" dwarf in blue and a normal disk dwarf population in the red.
