Upper panel: deviations from the microclumping approximation of equivalent widths of synthetic Hα line profiles versus mass-loss rate (see text). Clumping starts at 3cl = 0.24 and 0.06 (rcl = 1.3 and 1.05), respectively, as indicated in the figure. Lower panel: Hα line profiles as calculated by stochastic, analytic, and microclumped models with fcl=9 and Ṁ = 10 × 10-6 M⊙/yr, and the rest of the stellar and wind parameters as for λ Cep. Clumping for all models starts at 3cl = 0.24.
