Examples illustrating the sensitivity of the central depth of He I λ4471   and He II λ4541   to stellar rotation (vsini  = 60 (solid), 100 (dotted), 150 (dashed), 200 (dash-dotted) km s-1 ), and spectral resolution (R = 30   000 (top), 4000 (bottom)). Model profiles from fastwind, calculated at Teff  = 38 kK, log g  = 3.7 and log Q = −7.72, with log W′ = −0.19 corresponding to subtype O6.5.
