Comparison of physical and wind parameters of selected XShootU OB stars from this study with representative literature results based on optical diagnostics. All analyses involve FASTWIND (Puls et al. 2005; Rivero González et al. 2012) with the exception of Sk −71^∘ 41 which used PoWR (Gräfener et al. 2002; Sander et al. 2015).
