Three-colour photometry of early-type stars near the galactic poles
Abstract
Magnitudes and colours on the U, B, V system are presented for I 10 stars of early spectral type within 150 from the north galactic pole and for 110 stars within 120.5 from the south galactic pole (Lund system). Some effects of reddening and blanketing in the two-colour diagram are discussed. The Sculptoris Cluster is found to be at a distance of 250 pc; its age is about 3 X I0 years. The average absorption in its region is Av = mag.
