Empirical effective temperatures of late O, B, A and early F stars
Empirical effective temperatures of 99 late O, B, A and early F starshave been derived by combining space observations in the ultravioletwith ground-based observations and by fitting the computed fluxes to theobserved fluxes in the visible and ultraviolet spectral ranges.Effective temperatures found here are in good agreement with thosederived by previous workers.
