Scientific paper

We present a sample of faint blue stars at medium to high galactic latitude, and classify the stars as blue horizontal branch (BHB) or probable non-BHB stars on the basis of medium dispersion spectra and broadband photoelectric BV photometry. The classification scheme (Flynn et al. 1993) is as accurate as Stroemgren photometry. Using this method we have identified a sample of 100 BHB objects in the galactic halo to faint magnitudes (13.5 < V < 19.5), the selection criteria ensuring that the sample is the cleanest to date. We analyse the kinematics of the BHB stars in a subsequent paper.
