Fig. 8
Comparison of theoretical line profiles (solid curves) corresponding to a mass-loss rate of Ṁ = 2 × 10-6 M⊙ yr-1 and a wind velocity of ν∞ = 20 km s-1 with observations (dashed curves), including a velocity calibration provided by the UVES spectra (see Sect. 3.2.2) and a systemic velocity of −1.3 km s-1. The relative flux is given as a function of the observed radial velocity.
