The distribution of G5-M stars in a region at the south galactic pole
A survey has been conducted of an 81-sq deg area at the south galacticpole (SGP) in order to study the late-type star distribution as afunction of distance from the galactic plane. Both spectral types andluminosity classes are obtained from objective-prism spectra, usingclassification criteria closely associated with the MK classificationsystem. The SGP data are compiled into a catalog of 2228 stars of typeG5 and later, to a limiting magnitude of V=13.5 mag. An analysis of thedensity distribution of both dwarfs and giants indicates that the numberof dwarfs, as a function of magnitude, appears inconsistent with theassumption of a uniform density distribution for these stars.
