Wind momentum-luminosity diagram for O dwarfs, giants, and supergiants. Colors and geometric figures stand as in Fig. 8, our results are shown in red crosses. Our results are derived from the UV analysis. All the spectroscopic results consider (or are scaled to) unclumped Ṁ. The theoretical relation of Vink et al. (2000) is in solid black. We mark log (L_⋆ ∕L_⊙) = 5.2 in dashed black line, and representative error bars for the literature results are shown in the top left.
