Scientific paper

A survey has been conducted of an 81-sq deg area at the south galactic pole (SGP) in order to study the late-type star distribution as a function of distance from the galactic plane. Both spectral types and luminosity classes are obtained from objective-prism spectra, using classification criteria closely associated with the MK classification system. The SGP data are compiled into a catalog of 2228 stars of type G5 and later, to a limiting magnitude of V=13.5 mag. An analysis of the density distribution of both dwarfs and giants indicates that the number of dwarfs, as a function of magnitude, appears inconsistent with the assumption of a uniform density distribution for these stars.
