Abstract
The FN method is used to compute the classical X and Y functions for u se in the solution of a class of non-grey radiative-transfer problems defined for finite layers. The model considered allows for scattering with complete frequency redistribution (completely noncoherent scatter ing) and continuum absorption. Some test problems based on Doppler and Lorentz profiles of the line-scattering coefficient are discussed, an d numerical results (thought to be correct to five significant figures ) are given for selected cases.
