Faint F stars in the south galactic polar cap; Strömgren and Walraven photometry.
Abstract
WULBV (Walraven) photometry and uvby photometry for 50 F stars down to V = 11.8 in the McCormick proper-motion fields near the south galactic pole are discussed with emphasis on the metal abundance parameter. It is shown that the quantities delta(B-L) can serve well to measure metal abundance as an equivalent to delta m1. The distribution of delta m1 is shown for distances z = 300 to 600 pc, bearing out the intermediate Population II character of this sample.
