Scientific paper

The method developed by Underhill et al. (1979) is applied to P Cyg (B1 Iap), HD 190603 (B1 Ia+), kappa Cas (B1 Ia), and rho Leo (B1 Ib or Iab) using the S2/68 absolute UV photometry for faint stars (Thompson et al., 1978) and the 13-color photometry. Some profiles of the UV resonance lines are presented, and the implication of pertinent data for the interpretation of the observed UV spectrum of the winds from these stars is discussed.
