Notes.
The results for the wind from the rotating O-giant with the fixed stellar parameters given in the upper part of the table. The converged values of the wind parameters v∞, β, , γ, δ, 
, and mass-loss rates log Ṁ, together with the critical radius , which is equal (i.e. close) to the sonic radius (obtained by ISA-Wind), are displayed in the lower part of the table: the values of the first column (at the pole) are the results of the iteration cycle shown in the upper part of Table A.2, whereas the mean values for the equator in the second column were obtained from the parameter values of iteration step no 14 and 23, displayed in the lower part of Table A.2. (ρeq/ρp)∞ is the terminal ratio of the wind density at the equator compared to the pole.
