Values of $\dot{M}$ (top left), $\text{log}(\dot{M}\sqrt{f_{\text{cl}}})$ (top right) and T_eff (lower left) derived in this work compared to values found in literature. Studies that include clumping (either by fitting a clumping factor or assuming it) are shown in the $\dot{M}$-plot; studies that do not consider clumping are shown in the $\text{log}(\dot{M}\sqrt{f_{\text{cl}}})$-plot. The T_eff-plot contains all values. Blue symbols correspond to the presumed single stars, orange-red symbols to the stars with signs of binarity; various markers indicate different sources. In the corner of each panel the typical error bar of values derived in this work is shown. The majority of the literature values come from Massa et al. (2017) and Bestenlehner et al. (2025); these are marked in the plot (light blue hexagons and yellow squares, respectively). References to other studies included in this plot can be found in Tables F.1 and F.2. Values derived using quantitative optical and UV spectroscopy are marked with green circles. The black diagonal line indicates where the literature values equal ours, and the grey area corresponds to the systematic uncertainty that can be expected when analysing O-star spectra with different codes and methods (see Sander et al. 2024).
