The effect of scattering on the lineshape of outgoing 
radiation for the regular absorption band model is investigated for 
the model of a homogeneous plane-parallel radiating, absorbing, and 
scattering layer with transparent boundaries. The investigation is 
based on numerical solution of the integrodifferential equation of 
radiation transport. Based on an analysis of results obtained, methods 
more accurate than the known ones are proposed for calculation of 
the absorption coefficient by a selective component of the medium 
averaged over a finite spectral range.
