Comparison between pipeline temperatures (kK) and empirical wind velocities, v_∞, obtained either from SEI fits (quality i or ii filled symbols; quality iii open symbols) or v_black (open symbols) for OB dwarfs (blue circles), giants (red squares) and supergiants (black triangles), for the LMC (upper panel) and SMC (lower panel) together with the v_∞ − T_eff calibration from Hawcroft et al. (2024, solid black line).
