Hβ photometry of southern early-type stars and galactic structure away from the plane

H β photoelectric photometry is reported for 165 early-type stars at intermediate and high galactic latitudes. The data are combined with earlier UBV and spectroscopic results to determine the stellar space distribution. Stars of type B2 and earlier, at distances of up to 1 kpc from the galactic plane, appear to follow spiral structure in the plane. The available material, particularly the derived colour excesses, is used to select a number of blue stars which may be subluminous.
