Scientific paper

An analysis is made of the method of determination of effective temperatures for early-type stars from monochromatic and integrated fluxes. The essence of the method is a comparison of model predictions with the de-reddened ratio (observed monochromatic flux in the visual or infra-red)/(observed integrated flux), and solutions may be found graphically without iteration. Likely errors in effective temperature are at least 5 percent below 20,000 K, 10 percent at 30,000 K, and 20 percent at 40,000 K.
