Terminal velocities of our sample stars as a function of T_eff (blue diamonds indicate single stars, with hatched symbols corresponding to supergiants; white circles indicate binaries). In the background we show the best linear ODR fit to the single star observations of our sample (red solid line, v_∞ = 0.090T_eff 1175), as well as the LMC relation derived by Hawcroft et al. (2024b, shown as the orange dashed line, v_∞ = 0.085T_eff 1150). In the background we show in grey the trends of the theoretical predictions of Björklund et al. (2021, dash-dotted line), Vink & Sander (2021, dotted line), and Krtička & Kubát (2018, solid line). We note that one source, the binary LH 114-7 (v_∞ = 3425 km s^–1), falls outside the range of this plot due to its high effective temperature (T_eff = 59 000 K).
