Notes. The slow wind is defined as wind with speeds between 380 km s-1 and 420 km s-1, and the fast wind is defined as wind with speeds between 740 km s-1 and 780 km s-1. Details for how these quantities were derived can be found in Sect. 3 and the caption of Fig. 2. We mark with bold font the quantities we use to constrain the free parameters in the slow and fast wind models.
