Notes. The variable stellar and wind parameters at each iteration step until convergence. For the fixed stellar parameters L, T_eff, R, M, and Γ, see upper part of Table 1 in Sect. 4. The line acceleration parameters γ_fit (or equivalently β), δ_fit and , and the terminal velocity v_{∞,   fit}, were determined by (a simplified version of) fitting formula Eq. (71), applied to the results from a numerical calculation of the line acceleration at the equator (θ = π/2). The parameter (in the β velocity law, Eq. (64)) and the sonic radius are output values from ISA-Wind, whereas log   Ṁ is the improved estimated mass-loss rate numerically obtained (by MC-Wind and Eq. (74)). At each iteration step, the value of v_∞ was calculated by (a simplified version of) Eq. (75) and used as the new input value for the terminal velocity in the next iteration step, together with the new estimates of Ṁ and β (cf. description of iteration process in Sect. 3.3). Convergence is achieved when the values of v_{∞,   fit} and v_∞ have become equal or close to each other. In this case, the condition that the critical radius (determined by Eq. (42)) has to be equal to the sonic radius (determined by ISA-Wind) is fulfilled.
