(Top) Wind parameter space available for several SEDs that only differ in HR_hard. For better visualization, different panels showcase different angles of the same figure. (Bottom) Projections along two wind parameters, highlighting the differences between pairs of SEDs among the one displayed above. In the plane, combinations of the wind parameters only valid for the first (second) SED are shown with /// (\\\) hashes. When the first two wind parameters are compatible, the difference in the third wind parameter is highlighted with a color map in shades of orange (blue) if it is positive (negative).
