The three kinds of means which are generally used in construction of a model of a 'nongrey atmosphere' of a star are compared for three effective temperatures, 41',700, 20,400 and 10,700° K, with log g = 4.2. It is found that the kind of mean used does not show any wild influence on the physical parameters of the model. Thus, in general, for the study of 'nongrey stellar atmospheres' in mechanical equilibrium any kind of mean may be a good approximation.
