Illustrative spectra from our grid of models representing LMC and SMC OB stars. The displayed wavelength range spans from 500 Å to 30 000 Å. All models have a fixed log g = 4.0 and T_eff = 25, 35, 45 and 55 kK (bottom to top). Roughly, they correspond to an early B star, late, mid and early O star, respectively. Background colors correspond to different wavelength ranges as indicated by the top labels.
