Description:
The results of photoelectric UBV photometry of 234 AB stars in the
southern galactic halo are presented. The stars were chosen from the
Curtis Schmidt objective-prism survey of Preston and Shectman and
comprise a sample of halo objects selected without kinematic bias. The
majority of the stars lie in the region of the (U-B, B-V) plane
occupied by field and globular cluster blue horizontal-branch stars.
